Report from ICMR 2017

ACM International Conference on Multimedia Retrieval (ICMR) 2017

ACM ICMR 2017 in “Little Paris”

ACM ICMR is the premier International Conference on Multimedia Retrieval, and from 2011 it “illuminates the state of the arts in multimedia retrieval”. This year, ICMR was in an wonderful location: Bucharest, Romania also known as “Little Paris”. Every year at ICMR I learn something new. And here is what I learnt this year.

UNDERSTANDING THE TANGIBLE: object, scenes, semantic categories – everything we can see.

1) Objects (and YODA) can be easily tracked in videos.

Arnold Smeulders delivered a brilliant keynote on “things” retrieval: given an object in an image, can we find (and retrieve) it in other images, videos, and beyond? Very interesting technique for tracking objects (e.g. Yoda) in videos based on similarity learnt through siamese networks.

Tracking Yoda with Siamese Networks

2) Wearables + computer vision help explore cultural heritage sites.

As showed in his keynote, at MICC University of Florence, Alberto del Bimbo and his amazing team have designed smart audio guides for indoor and outdoor spaces. The system detects, recognises, and describes landmarks and artworks from wearable camera inputs (and GPS coordinates, in case of outdoor spaces).

3) We can finally quantify how much images provide complementary semantics compared to text [BEST MULTIMODAL PAPER AWARD].

For ages, the community has asked how relevant different modalities are for multimedia analysis: this paper (http://dl.acm.org/citation.cfm?id=3078991) finally proposes a solution to quantify information gaps between different modalities.

4) Exploring news corpuses is now very easy: news graphs are easy to navigate and aware of the type of relations between articles.

Remi Bois and his colleagues presented this framework (http://dl.acm.org/citation.cfm?id=3079023), made for professional journalists and the general public, for seamlessly browsing through large-scale news corpus. They built a graph where nodes are articles in a news corpus. The most relevant items to each article are chosen (and linked) based on an adaptive nearest neighbor technique. Each link is then characterised according to the type of relation of the 2 linked nodes.

5) Panorama outdoor images are much easier to localise.

In his beautiful work (https://t.co/3PHCZIrA4N), Ahmet Iscen from Inria developed an algorithm for location prediction from StreetView images, outperforming the state of the art thanks to an intelligent stitching pre-processing step: predicting locations from panoramas (stitched individual views) instead of individual street images improves performances dramatically!

UNDERSTANDING THE INTANGIBLE: artistic aspects, beauty, intent: everything we can perceive

1) Image search intent can be predicted by the way we look.

In his best paper candidate research work (http://dl.acm.org/citation.cfm?id=3078995), Mohammad Soleymani showed that image search intent (seeking information, finding content, or re-finding content) can be predicted from physisological responses (eye gaze) and implicit user interaction (mouse movements).

2) Real-time detection of fake tweets is now possible using user and textual cues.

Another best paper candidate (http://dl.acm.org/citation.cfm?id=3078979), this time from CERTH. The team collected a large dataset of fake/real sample tweets spanning 17 events and built an effective model from misleading content detection from tweet content and user characteristics. A live demo here: http://reveal-mklab.iti.gr/reveal/fake/

3) Music tracks have different functions in our daily lives.

Researchers from TU Delft have developed an algorithm (http://dl.acm.org/citation.cfm?id=3078997) which classifies music tracks according to their purpose in our daily activities: relax, study and workout.

4) By transferring image style we can make images more memorable!

The team at University of Trento built an automatic framework (https://arxiv.org/abs/1704.01745) to improve image memorability. A selector finds the style seeds (i.e. abstract paintings) which are likely to increase memorability of a given image, and after style transfer, the image will be more memorable!

5) Neural networks can help retrieve and discover child book illustrations.

In this amazing work (https://arxiv.org/pdf/1704.03057.pdf), motivated by real children experiences, Pinar and her team from Hacettepe University collected a large dataset of children book illustrations and found that neural networks can predict and transfer style, allowing to make “Winnie the witch”-like many other illustrations.

6) Locals perceive their neighborhood as less interesting, more dangerous and dirtier compared to non-locals.

In this wonderful work (http://www.idiap.ch/~gatica/publications/SantaniRuizGatica-icmr17.pdf), presented by Darshan Santain from IDIAP, researchers asked locals and crowd-workers to look at pictures from various neighborhoods in Guanajuato and rate them according to interestingness, cleanliness, and safety.

THE FUTURE: What’s Next?

1) We will be able to anonymize images of outdoor spaces thanks to Instagram filters, as proposed by this work (http://dl.acm.org/citation.cfm?id=3080543) in the Brave New Idea session.  When an image of an outdoor space is manipulated with appropriate Instagram filters, the location of the image can be masked from vision-based geolocation classifiers.

2) Soon we will be able to embed watermarks in our Deep Neural Network models in order to protect our intellectual property [BEST PAPER AWARD]. This is a disruptive, novel idea, and that is why this work from KDDI Research and Japan National Institute of Informatics won the best paper award. Congratulations!

3) Given an image view of an object, we will predict the other side of things (from Smeulders’ keynote). In the pic: predicting the other side of chairs. Beautiful.

Predicting the other side of things

THANKS: To the organisers, to the volunteers, and to all the authors for their beautiful work :)

Awarding the Best Social Media Reporters

The SIGMM Records team has adopted a new strategy to encourage the publication of information, and thus increase the chances to reach the community, increase knowledge and foster interaction. It consists of awarding the best Social Media reporters for each SIGMM conference, being the award a free registration to one of the SIGMM conference within a period of one year. All SIGMM members are welcome to participate and contribute, and are candidates to receive the award.

The Social Media Editors will issue a new open Call for Reports (CfR) via the Social Media channels every time a new SIGMM conference takes place, so the community can remember or be aware of this initiative, as well as can refresh its requirements and criteria.

The CfR will encourage activity on Social Media channels, posting information and contents related to the SIGMM conferences, with the proper hashtags (see our Recommendations). The reporters will be encouraged to mainly use Twitter, but other channels and innovative forms or trends of dissemination will be very welcome!

The Social Media Editors will be the jury for deciding the best reports (i.e., collection of posts) on Social Media channels, and thus will not qualify for this award. The awarded reporters will be additionally asked to provide a post-summary of the conference. The number of awards for each SIGMM conference is indicated in the table below. The awarded reporter will get a free registration to one of the SIGMM conferences (of his/her choice) within a period of one year.
