ESSENTIA: an open source library for audio analysis

Over the last decade, audio analysis has become a field of active research in academic and engineering worlds. It refers to the extraction of information and meaning from audio signals for analysis, classification, storage, retrieval, and synthesis, among other tasks. Related research topics challange understanding and modeling of sound and music, and develop methods and technologies that can be used to process audio in order to extract acoustically and musically relevant data and make use of this information. Audio analysis techniques are instrumental in the development of new audio-related products and services, because these techniques allow novel ways of interaction with sound and music. Essentia is an open-source C++ library for audio analysis and audio-based music information retrieval released under the Affero GPLv3 license (also available under proprietary license upon request). It contains an extensive collection of reusable algorithms which implement audio input/output functionality, standard digital signal processing blocks, statistical characterization of data, and a large set of spectral, temporal, tonal and high-level music descriptors that can be computed from audio. In addition, Essentia can be complemented with Gaia, a C++ library with python bindings which allows searching in a descriptor space using different similarity measures and classifying the results of audio analysis (same license terms apply). Gaia can be used to generate classification models that Essentia can use to compute high-level description of music. Essentia is not a framework, but rather a collection of algorithms wrapped in a library. It doesn’t enforce common high-level logic for descriptor computation (so you aren’t locked into a certain way of doing things). It rather focuses on the robustness, performance and optimality of the provided algorithms, as well as ease of use. The flow of the analysis is decided and implemented by the user, while Essentia is taking care of the implementation details of the algorithms being used. A number of examples are provided with the library, however they should not be considered as the only correct way of doing things. The library includes Python bindings as well as a number of predefined executable extractors for the available music descriptors, which facilitates its use for fast prototyping and allows setting up research experiments very rapidly. The extractors cover a number of common use-cases for researchers, for example, computing all available music descriptors for an audio track, extracting only spectral, rhythmic, or tonal descriptors, computing predominant melody and beat positions, and returning the results in yaml/json data formats. Furthermore, it includes a Vamp plugin to be used for visualization of music descriptors using hosts such as Sonic Visualiser. The library is cross-platform and supports Linux, Mac OS X and Windows systems. Essentia is designed with a focus on the robustness of the provided music descriptors and is optimized in terms of the computational cost of the algorithms. The provided functionality, specifically the music descriptors included out-of-the-box and signal processing algorithms, is easily expandable and allows for both research experiments and development of large-scale industrial applications. Essentia has been in development for more than 7 years incorporating the work of more than 20 researchers and developers through its history. The 2.0 version marked the first release to be publicly available as free software released under AGPLv3.

Algorithms

Essentia currently features the following algorithms (among others):

  • Audio file input/output: ability to read and write nearly all audio file formats (wav, mp3, ogg, flac, etc.)
  • Standard signal processing blocks: FFT, DCT, frame cutter, windowing, envelope, smoothing
  • Filters (FIR & IIR): low/high/band pass, band reject, DC removal, equal loudness
  • Statistical descriptors: median, mean, variance, power means, raw and central moments, spread, kurtosis, skewness, flatness
  • Time-domain descriptors: duration, loudness, LARM, Leq, Vickers’ loudness, zero-crossing-rate, log attack time and other signal envelope descriptors
  • Spectral descriptors: Bark/Mel/ERB bands, MFCC, GFCC, LPC, spectral peaks, complexity, rolloff, contrast, HFC, inharmonicity and dissonance
  • Tonal descriptors: Pitch salience function, predominant melody and pitch, HPCP (chroma) related features, chords, key and scale, tuning frequency
  • Rhythm descriptors: beat detection, BPM, onset detection, rhythm transform, beat loudness
  • Other high-level descriptors: danceability, dynamic complexity, audio segmentation, semantic annotations based on SVM classifiers

The complete list of algorithms is available online in the official documentation.

Architecture

The main purpose of Essentia is to serve as a library of signal-processing blocks. As such, it is intended to provide as many algorithms as possible, while trying to be as little intrusive as possible. Each processing block is called an Algorithm, and it has three different types of attributes: inputs, outputs and parameters. Algorithms can be combined into more complex ones, which are also instances of the base Algorithm class and behave in the same way. An example of such a composite algorithm is presented in the figure below. It shows a composite tonal key/scale extractor, which combines the algorithms for frame cutting, windowing, spectrum computation, spectral peaks detection, chroma features (HPCP) computation and finally the algorithm for key/scale estimation from the HPCP (itself a composite algorithm).

The algorithms can be used in two different modes: standard and streaming. The standard mode is imperative while the streaming mode is declarative. The standard mode requires to specifying the inputs and outputs for each algorithm and calling their processing function explicitly. If the user wants to run a network of connected algorithms, he/she will need to manually run each algorithm. The advantage of this mode is that it allows very rapid prototyping (especially when the python bindings are coupled with a scientific environment in python, such as ipython, numpy, and matplotlib).

The streaming mode, on the other hand, allows to define a network of connected algorithms, and then an internal scheduler takes care of passing data between the algorithms inputs and outputs and calling the algorithms in the appropriate order. The scheduler available in Essentia is optimized for analysis tasks, and does not take into account the latency of the network. For real-time applications, one could easily replace this scheduler with another one that favors latency over throughput. The advantage of this mode is that it results in simpler and safer code (as the user only needs to create algorithms and connect them, there is no room for him to make mistakes in the execution order of the algorithms), and in lower memory consumption in general, as the data is streamed through the network instead of being loaded entirely in memory (which is the usual case when working with the standard mode). Even though most of the algorithms are available for both the standard and streaming mode, the code that implements them is not duplicated as either the streaming version of an algorithm is deduced/wrapped from its standard implementation, or vice versa.

Applications

Essentia has served in a large number of research activities conducted at Music Technology Group since 2006. It has been used for music classification, semantic autotagging, music similarity and recommendation, visualization and interaction with music, sound indexing, musical instruments detection, cover detection, beat detection, and acoustic analysis of stimuli for neuroimaging studies. Essentia and Gaia have been used extensively in a number of research projects and industrial applications. As an example, both libraries are employed for large-scale indexing and content-based search of sound recordings within Freesound, a popular repository of Creative Commons licensed audio samples. In particular, Freesound uses audio based similarity to recommend sounds similar to user queries. Dunya is a web-based software application using Essentia that lets users interact with an audio music collection through the use of musical concepts that are derived from a specific musical culture, in this case Carnatic music.

Examples

Essentia can be easily used via its python bindings. Below is a quick illustration of Essentia’s possibilities for example on detecting beat positions of music track and its predominant melody in a few lines of python code using the standard mode:


from essentia.standard import *; audio = MonoLoader(filename = 'audio.mp3')(); beats, bconfidence = BeatTrackerMultiFeature()(audio); print beats; audio = EqualLoudness()(audio); melody, mconfidence = PredominantMelody(guessUnvoiced=True, frameSize=2048, hopSize=128)(audio); print melody Another python example for computation of MFCC features using the streaming mode: from essentia.streaming import * loader = MonoLoader(filename = 'audio.mp3') frameCutter = FrameCutter(frameSize = 1024, hopSize = 512) w = Windowing(type = 'hann') spectrum = Spectrum() mfcc = MFCC() pool = essentia.Pool() # connect all algorithms into a network loader.audio >> frameCutter.signal frameCutter.frame >> w.frame >> spectrum.frame spectrum.spectrum >> mfcc.spectrum mfcc.mfcc >> (pool, 'mfcc') mfcc.bands >> (pool, 'mfcc_bands') # compute network essentia.run(loader) print pool['mfcc'] print pool['mfcc_bands'] Vamp plugin provided with Essentia allows to use many of its algorithms via the graphical interface of Sonic Visualiser. In this example, positions of onsets are computed for a music piece (marked in red): An interested reader is referred to the documention online for more example applications built on top of Essentia.

Most cited papers before the era of ICMR

In the early years of 2000, the field of multimedia retrieval was composed of special sessions at conferences and small workshops. There were no multimedia retrieval conferences. One of the leading workshops (B. Kerherve, V. Oria and S. Satoh) was the ACM SIGMM Workshop on Multimedia Information Retrieval (MIR) which was held with the ACM MM conference.

To have a central meeting for the scientific community, the International Conference on Image and Video Retrieval (CIVR) was founded in 2002 (J. Eakins, P. Enser, M. Graham, M.S. Lew, P. Lewis and A. Smeaton). Both meetings evolved over the next decade.  CIVR and MIR became ACM SIGMM sponsored conferences and established reputations for high quality work.

In 2010, the steering committees of both CIVR and MIR voted to combine the two conferences toward unifying the communities and establishing the ACM flagship meeting for multimedia retrieval, the ACM International Conference on Multimedia Retrieval (ICMR).  In 2013, ICMR was ranked by the Chinese Computing Federation as the #1 meeting in multimedia retrieval and the #4 meeting in the wide domain of Multimedia and Graphics.

For archival reasons, this is a summary of which papers had the most citations from ACM CIVR and ACM MIR (2008-2010), based on Google Scholar data in the period from February 17-18, 2014.

Google Scholar citations were used because they have wide coverage (ACM, IEEE, Springer, Elsevier, etc.), are publicly accessible and because they are being increasingly accepted by researchers for both paper citations estimates and computing the h-index.

Innovations made for Multimedia 2013:

In attempt to continuously improve ACM Multimedia and ensure its vibrant role for the multimedia community, we have made a number of enhancements for this year’s conference:

  • The Technical Program Committee defined twelve Technical Areas for major focus for this year’s conference, including introducing new Technical Areas for Music & Audio and Crowdsourcing to reflect their growing interest and promise. We have also changed the names of some traditional Technical Areas and provided extensive description of each area to help the authors choosing the most appropriate Technical Area for their manuscripts.
  • We have introduced a new role in the organization of the conference: the author’s advocate. His explicit role was to listen to the authors, and to help them if reviews are clearly below average quality. The authors could request the mediation of the author’s advocate after the reviews have been sent to them and they had to clearly justify the reasons why such mediation is needed (the reviews or the meta-review were below average quality). The task of the advocate was to investigate carefully the matter and to request additional review or reexamination of the decision of the particular manuscript. This year, the author’s advocate was Pablo Cesar from CWI, The Netherlands.
  • We have decided to keep a couple of plenary sessions which will bring singular focus to conference activities: keynotes, Multimedia Grand Challenge competition, Best Paper session, Technical Achievement Award and Best PhD Award sessions. The other technical sessions are held in parallel to allow pursuit of more specialized interests at the conference. We have limited the number of parallel session to no more than 3 to minimize the risk of having overlapping interests.
  • The use of video spotlights for advertising the works to be presented. These were meant to offer all attendees an opportunity to become aware of the content of each paper, and thus to be attracted to attend the corresponding poster or talk.
  • Workshops and Tutorials are held on separate days from the main conference in order to reduce conflict with the regular Technical Program.
  • The Multimedia Art Exhibition featured both invited and selected artists. It was open for the duration of the conference in the satellite venue located in the center of the city.
  • Following the last two years’ precedent, Tutorials are made free for all participants.
  • Recognizing that students are the lifeblood of our next generation of multimedia thinkers, this year’s Student Travel Grant was greatly expanded. We had a total amount of $26,000 received from SIGMM ($16,000) and NSF ($10,000) that supported 35 students.
  • Finally, we have decided to provide open access for the community to the proceedings available in the ACM Digital Libraries. As such, no USB proceedings were handed over to the participants encouraging everyone to get online access.

Technical Program

Following the guidelines of the ACM Multimedia Review Committee, the conference was structured into 12 Areas, with a two-tier TPC, a double-blind review process, and a target acceptance rate of 20% for long papers and 27.7% for short papers. Based on the experience from ACM Multimedia 2012 and the responses to our “Call for Areas” that we issued to the community, we selected the following Areas.

  1. Art, Entertainment, and Culture
  2. Authoring and Collaboration
  3. Crowdsourcing
  4. Media Transport and Delivery
  5. Mobile & Multi-device
  6. Multimedia Analysis
  7. Multimedia HCI
  8. Music & Audio
  9. Search, Browsing, and Discovery
  10. Security and Forensics
  11. Social Media & Presence
  12. Systems and Middleware

The Technical Program Committee was first created by appointing Area Chairs (ACs). A total of 29 colleagues agreed to serve in this role. Each Area was represented by two ACs, with exception of two Areas (Multimedia Analysis and Search, Browsing, and Discovery) whose scope has traditionally attracted the largest proportion of papers and so required further coordination. The added topic diversity brought an increase in gender diversity to the ACs, which increased from approximately 12% in previous years to 22% for 2013. We also made a conscious effort to bring new talent and excellence into the community and to better represent emerging trends in the field. For this we appointed many young and well recognized ACs who served in this role for the first time. For each junior AC, we co-appointed a senior researcher as their co-AC to aid in their shepherding. In a second step, the Area Chairs were responsible for appointing the TPC members (reviewers) for their coordinated areas. This was a large effort to grow the TPC base for the conference as well as ensure proper expertise was represented in each area. We coupled this with a hard goal of limiting the number of submissions assigned to each TPC member for review. For example, two years ago, the average number of papers assigned to a reviewer was 9 with over 38% of the approximately 225 TPC members receiving 10 or more papers to review. With our design, we had a total of 398 reviewers receiving an average of 4.13 papers per reviewer. While we were unable to keep a hard ceiling limitation, only 2.51% of the TPC received 10 or more papers to review—all TPC members who had agreed to serve in more than one area. The Area Chairs were in charge of assigning all papers for review, and each submission was reviewed double-blind by three TPC members. Reviews and reviewer assignments of papers co-authored by Area Chairs, Program Chairs, and General Chairs were handled by Program Chairs who had no conflicts of interest for each specific case. Another novelty introduced in the reviewing process was to set the paper submission deadline to a significantly earlier date than previous years, in order to allocate more time for reviews, rebuttals, discussions, and final decisions. Despite the reduced time given to authors, the response to the Call for Papers was enthusiastic with a total of 235 long papers and 278 short papers going through review. The authors of long papers were asked to write a rebuttal after receiving the reviews. A new element in the reviewing process was the introduction of the Author’s Advocate figure, created to provide authors with an independent channel to express concerns about the quality of the reviews for their papers, and to raise a flag about these reviews. All cases were brought to the attention to the corresponding Area Chair. After evaluating each case reported to him (16 reviews out of 761 long paper reviews), the Author’s Advocate recommended in 5 cases that new reviews were generated and added to the discussion. The reviewers had a period for on-line discussion of reviews and rebuttals, after which the Area Chairs drafted a meta-review for each paper. Decisions on long and short papers were made at the TPC meeting held at the University of Amsterdam on June 11, 2013. The meeting was physically attended by one of the General Chairs, three of the Program Chairs, the Author’s Advocate, and 86% of the ACs. Many of the ACs who were unable to attend were tele-present online for discussions. On the first half day of the TPC meeting, the Area Chairs worked in breakout sessions to discuss the papers that were weak accepts and weak rejects, with the exception of conflict of interest papers which were handled out of band as previously mentioned. In the second half of the first day, the ACs met in a plenary session where they reviewed the clear accepts and defended the decisions on the borderline papers based on the papers themselves, reviews, meta-reviews, on-line discussions, and authors’ rebuttal comments. In many cases, an emergency reviewer was added if there was clear intersection with a related submission area. If a paper had any conflict of interest during the plenary session with an Area, Program, or General Chair, they were excused from the room. On June 12, 2013, the Program Chairs finalized the process and conference program in a separate meeting—arranging the sessions by thematic narratives and not by submission area to promote cross-area conversations during the conference itself. The review process resulted in an overall acceptance rate of 20.0% for long papers and 27.7% for short papers (the distribution of submissions and the acceptance rate for each one of the 12 areas is shown in the graph below). All accepted long papers were shepherded by the Area Chairs themselves or by qualified TPC members who were in charge of verifying that the revised papers adequately addressed concerns raised by the reviewers and changes promised by authors in their rebuttals. This step ensured that all of the accepted papers are of the highest quality possible. In addition, four papers with high review scores were nominated at the TPC meeting as candidates for the Best Paper Award. Each nominated paper had to be successfully championed and defended by the ACs from that area. The winner was announced at the Conference Banquet.

Multimedia Framed Dr. Elizabeth F. Churchill (Ebay Research Labs) Wednesday, Oct. 23, 2013 Abstract: Multimedia is the combination of several media forms. Information designers, educationalists and artists are concerned with questions such as: Is text, or audio or video, or a combination of all three, the best format for the message? Should another modality (e.g., haptics/touch, olfaction) be invoked instead to make the message more effective and/or the experience more engaging? How does the setting affect perception/reception? How does framing affect people’s experience of multimedia? How is the artifact changed through interaction with audience members? In this presentation, I will talk about people’s experience of multimedia artifacts like videos. I will discuss the ways in which framing affects how we experience multimedia. Framing can be intentional–scripted creations produced with clear intent by technologists, designers, media producers, media artists, film-makers, archivists, documentarians and architects. Framing can also be unintentional. Everyday acts of interest and consumption turn us, the viewers, into co-producers of the experiences of the multimedia artifacts we have viewed. We download, annotate, comment and share multimedia artifacts online. Our actions are reflected in view counts, displayed comments and content ranking. Our actions therefore change how multimedia artifacts are interpreted and understood by others. Drawing on examples from the history of film and of performance art, from current social media research and from research conducted with collaborators over the past 16 years, I will illustrate how content understanding is modulated by context, by the “framing” of the content. I will consider three areas of research that are addressing the issue of framing, and that have implications for our understanding of ‘multimedia’ consumption, now and in the future: (1) The psychology and psychophysiology of multimedia as multimodal experience; (2) Emerging practices with contemporary social media capture and sharing from personal devices; and (3) Innovations in social media and audience analytics focused on more deeply understanding media consumption. I will conclude with some technical excitements, design/development challenges and experiential possibilities that lie ahead. Dr. Elizabeth Churchill is Director of Human Computer Interaction at eBay Research Labs (ERL) in San Jose, California. Formerly a Principal Research Scientist at Yahoo!

She is a Distinguished Visiting Scholar at Stanford University’s Media X, the industry affiliate program to Stanford’s H-STAR Institute. The Space between the Images Leonidas J. Guibas (Stanford University) Thursday, Oct. 24, 2013 Abstract: Multimedia content has become a ubiquitous presence on all our computing devices, spanning the gamut from live content captured by device sensors such as smartphone cameras to immense databases of images, audio and video stored in the cloud. As we try to maximize the utility and value of all these petabytes of content, we often do so by analyzing each piece of data individually and foregoing a deeper analysis of the relationships between the media. Yet with more and more data, there will be more and more connections and correlations, because the data captured comes from the same or similar objects, or because of particular repetitions, symmetries or other relations and self-relations that the data sources satisfy. This is particularly true for media of a geometric character, such as GPS traces, images, videos, 3D scans, 3D models, etc. In this talk we focus on the “space between the images”, that is on expressing the relationships between different multimedia data items. We aim to make such relationships explicit, tangible, first class objects that themselves can be analyzed, stored, and queried — irrespective of the media they originate from. We discuss mathematical and algorithmic issues on how to represent and compute relationships or mappings between media data sets at multiple levels of detail. We also show how to analyze and leverage networks of maps and relationships, small and large, between inter-related data. The network can act as a regularizer, allowing us to to benefit from the “wisdom of the collection” in performing operations on individual data sets or in map inference between them. We will illustrate these ideas using examples from the realm of 2D images and 3D scans/shapes — but these notions are more generally applicable to the analysis of videos, graphs, acoustic data, biological data such as microarrays, homeworks in MOOCs, etc. This is an overview of joint work with multiple collaborators, as will be discussed in the talk. Prof. Leonidas Guibas obtained his Ph.D. from Stanford under the supervision of Donald Knuth. His main subsequent employers were Xerox PARC, DEC/SRC, MIT, and Stanford. He is currently the Paul Pigott Professor of Computer Science (and by courtesy, Electrical Engineering) at Stanford University. He heads the Geometric Computation group and is part of the Graphics Laboratory, the AI Laboratory, the Bio-X Program, and the Institute for Computational and Mathematical Engineering. Professor Guibas’ interests span geometric data analysis, computational geometry, geometric modeling, computer graphics, computer vision, robotics, ad hoc communication and sensor networks, and discrete algorithms. Some well-known past accomplishments include the analysis of double hashing, red-black trees, the quad-edge data structure, Voronoi-Delaunay algorithms, the Earth Mover’s distance, Kinetic Data Structures (KDS), Metropolis light transport, and the Heat-Kernel Signature. Professor Guibas is an ACM Fellow, an IEEE Fellow and winner of the ACM Allen Newell award.

SIGMM Talks

SIGMM Achievement Award Talk Dick Bulterman, CWI, The Netherlands Friday, Oct. 25, 2013 The 2013 winner of SIGMM award for Outstanding Technical Contributions to Multimedia Computing, Communications and Applications is Prof. Dr. Dick Bulterman. The ACM SIGMM Technical Achievement award is given in recognition of outstanding contributions over a researcher’s career. Prof. Dick Bulterman has been selected for his outstanding technical contributions in multimedia authoring, media annotation, and social sharing from research through standardization to entrepreneurship, and in particular for promoting international Web standards for multimedia authoring and presentation (SMIL) in the W3C Synchronized Multimedia Working Group as well as his dedicated involvement in the SIGMM research community for many years. Dr. Dick Bulterman has been a long time intellectual leader in the area of temporal modeling and support for complex multimedia system. His research has led to the development of several widely used multimedia authoring systems and players. He developed the Amsterdam Hypermedia Model, the CMIF document structure, the CMIFed authoring environment, the GRiNS editor and player, and a host of multimedia demonstrator applications. In 1999, he started the CWI spinoff company called Oratrix Development BV, and he worked as CEO to widely deliver this software. He is currently a Research Group Head of the Distributed and Interactive Systems at Centrum Wiskunde & Informatica (CWI) in Amsterdam, The Netherlands. He is also a Full Professor of Computer Science at Vrije Universiteit, Amsterdam. His research interests are multimedia authoring and document processing. Dick has a strong international reputation for the development of the domain-specific temporal language for multimedia (SMIL). Much of this software has been incorporated into the widely used Ambulant Open Source SMIL Player, which has served to encourage development and use of time-based multimedia content. His conference publications and book on SMIL have helped to promote SMIL and its acceptance as a W3C standard. Dick’s recent work on social sharing of video will likely prove influential in upcoming Interactive TV products. This work has already been recognized in the academic community, earning the ACM SIGMM best paper award at ACM MM 2008 and also at the EUROITV conference. SIGMM Ph.D Thesis Award Talk Xirong Li, Remin University, China Friday, Oct. 25, 2013 The SIGMM Ph.D. Thesis Award Committee recommended this year’s award for the outstanding Ph.D. thesis in multimedia computing, communications and applications to Dr. Xirong Li. The committee considered Dr. Li’s dissertation titled “Content-based visual search learned from social media” as worthy of the award as it substantially extends the boundaries for developing content-based multimedia indexing and retrieval solutions. In particular, it provides fresh new insights into the possibilities for realizing image retrieval solutions in the presence of vast information that can be drawn from the social media. The committee considered the main innovation of Dr. Li’s work to be in the development of the theory and algorithms providing answers to the following challenging research questions: (a) what determines the relevance of a social tag with respect to an image, (b) how to fuse tag relevance estimators, (c) which social images are the informative negative examples for concept learning, (d) how to exploit socially tagged images for visual search and (e) how to personalize automatic image tagging with respect to a user’s preferences. The significance of the developed theory and algorithms lies in their power to enable effective and efficient deployment of the information collected from the social media to enhance the datasets that can be used to learn automatic image indexing mechanisms (visual concept detection) and to make this learning more personalized for the user. Dr. Xirong Li received the B.Sc. and M.Sc. degrees from the Tsinghua University, China, in 2005 and 2007, respectively, and the Ph.D. degree from the University of Amsterdam, The Netherlands, in 2012, all in computer science. The title of his thesis is “Content-based visual search learned from social media”. He is currently an Assistant Professor in the Key Lab of Data Engineering and Knowledge Engineering, Renmin University of China. His research interest is image search and multimedia content analysis. Dr. Li received the IEEE Transactions on Multimedia Prize Paper Award 2012, Best Paper Nominee of the ACM International Conference on Multimedia Retrieval 2012, Chinese Government Award for Outstanding Self-Financed Students Abroad 2011, and the Best Paper Award of the ACM International Conference on Image and Video Retrieval 2010. He served as publicity co-chair for ICMR 2013. Panel Cross-Media Analysis and Mining Wednesday, Oct 23, 2013 Panelists:Mark Zhang, Alberto del Bimbo, Selcuk Candan, Alexander Hauptmann, Ramesh Jain, Alexis Joly, Yueting Zhuang Motivation Today there are lots of heterogeneous and homogeneous media data from multiple sources, such as news media websites, microblog, mobile phone, social networking websites, and photo/video sharing websites. Integrated together these media data represent different aspects of the real-world and help document the evolution of the world. Consequently, it is impossible to correctly conceive and to appropriately understand the world without exploiting the data available on these different sources of rich multimedia content simultaneously and synergistically. Cross-media analysis and mining is a research area in the general field of multimedia content analysis which focuses on the exploitation of the data with different modalities from multiple sources simultaneously and synergistically to discover knowledge and understand the world. Specifically, we emphasize two essential elements in the study of cross-media analysis that help differentiate cross-media analysis from the rest of the research in multimedia content analysis or machine learning. The first is the simultaneous co-existence of data from two or more different data sources. This element indicates the concept of “cross”, e.g., cross-modality, cross-source, and cross cyberspace to reality. Cross-modality means that heterogeneous features are obtained from the data in different modalities; cross-source means that the data may be obtained across multiple sources (domains or collections); cross-space means that the virtual world (i.e., cyberspace) and the real world (i.e., reality) complement each other. The second is the leverage of different types of data across multiple sources for strengthening the knowledge discovery, for example, discovering the (latent) correlation or synergy between the data with different modalities across multiple sources, transferring the knowledge learned from one domain (e.g., a modality or a space) to generate knowledge in another related domain, and generating a summary with the data from multiple sources. There two essential elements help promote cross-media analysis and mining as a new, emerging, and important research area in today’s multimedia research. With the emphasis on knowledge discovery, cross-media analysis is different from the traditional research areas such as cross-lingual translation. On the other hand, with the general scenarios of the leverage of different types of data across multiple sources for strengthening the knowledge discovery, cross-media analysis and mining addresses a broader series of problems than the traditional research areas such as transfer learning. Overall, cross-media analysis and mining is beneficial for many applications in data mining, causal inference, machine learning, multimedia, and public security. Like other emerging hot topics in multimedia research, cross-media analysis and mining also has a number of fundamental and controversial issues that must be addressed in order to have a full and complete understanding of the research in this topic. These issues include but are not limited to whether or not there exists a unified representation or modeling for the same semantic concept from different media, and if there is what such unified representation or modeling is; whether or not there exists any “law” that governs the topic evolution and development over the time in different media and if there is what such “law” is and how it is formulated; whether or not there exists a mapping for a conceptual or semantic activity between the cyberspace and the real-world, and if there is what such a mapping is and how it is developed and formulated. Brave New Idea Program Brave New Ideas addressed long term research challenges, pointed to new research directions, or provided new insights or brave perspectives that pave the way to innovation. The selection process was different from the regular papers. First, submission of a 2 page abstract was requested. Then, the first selection was performed and a full paper was required for the selected abstracts and reviewed and chosen. We received 38 submissions for the first stage and 14 were invited to submit the full paper for the second reviewing stage. Finally, there were accepted 6 papers, which formed two sessions of oral presentations. Multimedia Grand Challenge Solutions We had received six challenges as shown below for the Multimedia Grand Challenge Solutions Program.

  1. NHK – Where is beauty? Grand Challenge
  2. Technicolor – Rich Multimedia Retrieval from Input Videos Grand Challenge
  3. Yahoo! – Large-scale Flickr-tag Image Classification Grand Challenge

We received 34 proposals for this program, and 14 of them were accepted for the presentation. In order to promote submissions, all presentations in this program were awarded as Multimedia Grand Challenge Finalists. The best prize and two second best prizes were chosen and awarded. Requested by Technicolor, the Grand Challenge Multimodal Prize was also chosen and awarded. Technical Demonstrations We have received 80 excellent technical demonstrations proposals. The number of submissions was in line to the demonstrations received in the previous year. Three reviewers were assigned to each demo proposal, and finally 40 proposals were chosen. The best demo prize was awarded. Open Source Software Competition This year was the 6th edition of the Open software competition being part of the ACM Multimedia program. The goal of this competition is to praise the invaluable contribution of researchers and software developers who advance the field by providing the community with implementations of codecs, middleware, frameworks, toolkits, libraries, applications, and other multimedia software. This year we have received 16 submissions and after assigning three reviewers to each of them we have selected 11 for the competition. The best open source software was awarded. Doctoral Symposium Doctoral Symposium was meant as a forum for mentoring graduate students. It was held in the afternoon of Oct. 25 both in the oral and poster formats. We have received 19 proposals for doctoral symposium. We accepted 13 presentations (6 oral + poster and 7 additional posters). Additionally, there was organized a Doctoral Symposium lunch in which the students had the opportunity to talk to their assigned mentors. Finally, the best doctoral symposium paper was awarded. Multimedia Art Exhibition and Reception ACM Multimedia provided a rich Multimedia Art Exhibition to stimulate artists and researchers alike to meet and discover the frontiers of multimedia artistic communication. The Art Exhibition has attracted significant work from a variety of digital artists collaborating with research institutions. We have endeavored to select exhibits that achieved an interesting balance between technology and artistic intent. The techniques underpinning these artworks are relevant to several technical tracks of the conference, in particular those dealing with human-centered and interactive media. We had a satellite venue, FAD (Forment de les Arts i del Disseny), for the art exhibition located in the center of the city. The venue had a very good public access. The exhibition was open from Oct. 21 to Oct. 28 and visited by more than 2,000 visitors. The reception event was held with the artists on Oct. 23. We had selected 10 art works for the exhibition:

Survey

In order to gather opinions from the participants at ACM Multimedia 2013 we have performed a post-conference survey and the results are summarized in Appendix C. Here we summarize the 10 most important issues that were compiled after analyzing the answers received. The effort to gather all this information is the first of its kind at ACM Multimedia and we hope this tradition will be continued in the future. The results of the survey represent in our opinion a very good source of information for the future organizers.

  1. Poster space too small
  2. Many people still want USB proceedings!!
  3. Oral topics in the same time slot overlapped too much. Need to diversify.
  4. Need to attract more multimedia niche topics. Should not become a second rate CV conference
  5. First day location hard to find. Workshop/tutorial better to be co-located with main conference
  6. Senior members of MM community should participate in paper sessions more
  7. Need to update web site program content and make it available earlier
  8. Consider offering short spotlight talks for poster papers
  9. Keep 15 mins for oral, but have them presented again in poster session for more discussion
  10. SIGMM business meeting too long. Not enough time for QA.

Conclusion

ACM Multimedia 2013 was a great success with a great number of submissions, an excellent technical program, attractive program components, and stimulating events. As a result, we welcomed a large number of participants, in line with our initial expectation. There were a few problems see above but this is only natural. We greatly acknowledge those who have contributed to the success of ACM Multimedia 2013. We thank the organizers of ACM Multimedia 2012 for their useful suggestions and comments which helped us to improve the organization the 2013 edition. We also thank them for giving us the template for the conference booklet. We thank the many paper authors and proposal contributors for the various technical and program components. We thank the large number of volunteers, including the Organizing Committee members and Technical Program Committee members who worked very hard to create this year’s outstanding conference. Every aspect of the conference was also aided by local committee members and by the hard work of Grupo Pacifico, to whom we are very grateful. We thank also ACM staff and Sheridan Printing Company for their constant support. This success was clearly due to the integration of their efforts.

MPEG Column: 107th MPEG Meeting

Plenary during the 107th MPEG Meeting.

— original posts here and here by Multimedia Communication blog and bitmovin techblogChristian TimmererAAU/bitmovin

The MPEG-2 Transport Stream (M2TS; formally known as Rec. ITU-T H.222.0 | ISO/IEC 13818-1) has been awarded with the Technology & Engineering Emmy® Award by the National Academy of Television Arts & Sciences. It is the fourth time MPEG received an Emmy award. The M2TS is widely deployed across a broad range of application domain such as broadcast, cable TV, Internet TV (IPTV and OTT), and Blu-ray Disks. The Emmy was received during this year’s CES2014 in Las Vegas.

Plenary during the 107th MPEG Meeting.

Other topics of the 107th MPEG meeting in San Jose include the following highlights:

  • Requirements: Call for Proposals on Screen Content jointly with ITU-T’s Video Coding Experts Group (VCEG)
  • Systems: Committee Draft for Green Metadata
  • Video: Study Text Committee Draft for Compact Descriptors for Visual Search (CDVS)
  • JCT-VC: Draft Amendment for HEVC Scalable Extensions (SHVC)
  • JCT-3D: Proposed Draft Amendment for HEVC 3D Extensions (3D-HEVC)
  • Audio: 3D audio plans to progress to CD at 108th meeting
  • 3D Graphics: Working Draft 4.0 of Augmented Reality Application Format (ARAF) 2nd Edition

The official MPEG press release can be downloaded from the MPEG Web site. Some of the above highlighted topics will be detailed in the following and, of course, there’s an update on DASH-related matters at the end.

Call for Proposals on Screen Content

Screen content refers to content coming not from cameras but from screen/desktop sharing and collaboration, cloud computing and gaming, wirelessly connected displays, control rooms with high resolution display walls, virtual desktop infrastructures, tablets as secondary displays, PC over IP, ultra-thin client technology, etc. Also mixed-content is within the scope of this work item and may contain a mixture of camera-captured video and images with rendered computer-generated graphics, text, animation, etc.

Although this type of content was considered during the course of the HEVC standardization, recent studies in MPEG have led to the conclusion that significant further improvements in coding efficiency can be obtained by exploiting the characteristics of screen content and, thus, a Call for Proposals (CfP) is being issued for developing possible future extensions of the HEVC standard.

Companies and organizations are invited to submit proposals in response to this call –issued jointly by MPEG with ITU-T VCEG. Responses are expected to be submitted by early March, and will be evaluated during the 108th MPEG meeting. The timeline is as follows:

  • 2014/01/17: Final Call for Proposals
  • 2014/01/22: Availability of anchors and end of editing period for Final CfP
  • 2014/02/10: Mandatory registration deadline
    One of the contact persons (see Section 10) must be notified, and an invoice for the testing fee will be sent after registration. Additional logistic information will also be sent to proponents by this date.
  • 2014/03/05: Coded test material shall be available at the test site. By this date, the payment of the testing fee is expected to be finalized.
  • 2014/03/17: Submission of all documents and requested data associated with the proposal.
  • 2014/03/27-04/04: Evaluation of proposals at standardization meeting.
  • 2015: Final draft standard expected.

It will be interesting to see the coding efficiency of the submitted proposals compared to a pure HEVC or even AVC approach.

Committee Draft for Green Metadata

Green Metadata, formerly known as Green MPEG, shall enable energy-efficient media consumption and reached Committee Draft (CD) status at the 107th MPEG meeting. The representation formats defined within Green Metadata help reducing decoder power consumption and display power consumption. Clients may utilize such information for the adaptive selection of operating voltage or clock frequencies within their chipsets. Additional, it may be used to set the brightness of the backlights for the display to save power consumption.

Green Metadata also provides metadata for the signaling and selection of DASH representations to enable the reduction of power consumption for their encoding.

The main challenge in terms of adoption of this kind of technology is how to exploit these representation formats to actually achieve energy-efficient media consumption and how much!

What’s new on the DASH frontier?

The text of ISO/IEC 23009-1 2nd edition PDAM1 has been approved which may be referred to as MPEG-DASH v3 (once finalized and integrated into the second edition, possibly with further amendments and corrigenda, if applicable). This first amendment to MPEG-DASH v2 comprises accurate time synchronization between server and client for live services as well as a new profile, i.e., ISOBMFF High Profile which basically combines the ISOBMFF Live and ISOBMFF On-demand profiles and adds the Xlink feature.

Additionally, a second amendment to MPEG-DASH v2 has been started featuring Spatial Relationship Description (SRD) and DASH Client Authentication and Content Access Authorization (DAA).

Other DASH-related aspects include the following:

  • The common encryption for ISOBMFF has been extended with a simple pattern-based encryption mode, i.e., a new method which should simply content encryption.
  • The CD has been approved for the carriage of timed metadata metrics of media in ISOBMFF. This allows for the signaling of quality metrics within the segments enabling QoE-aware DASH clients.

What else? That is, some publicly available MPEG output documents… (Dates indicate availability and end of editing period, if applicable, using the following format YY/MM/DD):
