Please help in advancing scientific research in privacy protection in video surveillance

Could you please spare a few seconds and participate in the evaluation of visual privacy filters in video surveillance using this Facebook app: https://ltslinux18.epfl.ch/? The application was developed by MMSPG @EPFL and uses crowdsourcing approach to evaluate Visual Privacy filters (blurring, pixelization, and masking).

There are 9 videos of 10 seconds each in total with 6 Yes/No questions at the end of each video. You may help in evaluation of any number of videos. The application can run on major browsers.

If you could also spread the link to the application (https://ltslinux18.epfl.ch/) among your group members and any mailing lists, we would greatly appreciate it.

TOKYO, JAPAN, February 23rd (Wed.), 2011

Over a trillion pictures have been created in JPEG format and this trend continues. Millions of images are shared every day among friends and family in e-mails, photo-hosting Web sites and the enormously popular social networking sites, like Facebook and Flickr, where users can even instantly upload photos taken with their mobile phone cameras. Digital photos are also widely printed at homes or through commercial printing services.

Digital technology has given photographers creative tools and many new modes of distribution. It has also contributed to the progress of e-commerce, where digital images offer new opportunities in form of products and services. One enabler of this phenomenon has been the availability of powerful and inexpensive digital cameras. An enabler of this digital imaging ecosystem has been the existence of standard image coding formats produced by the Joint Photographic Experts Group (JPEG), a joint committee between the International Organization for Standardization (ISO) and the International Telecommunication Union's Telecommunication Standardization Sector (ITU-T).

The nature of digital photography is changing. In addition to increasing resolution, the dynamic range of sensors in digital cameras has been increasing enabling more vivid, higher contrast and life-like color images. More recently, 3D cameras allow for creation of stereo imagery. New standards may be required to accelerate adoption of such products and services by the market, as it was the case with the original JPEG standard.

The JPEG committee has created an activity called JPEG Innovations with the goal of promoting its existing standards and specifications to potential users, as well as exploring new opportunities for adoption of specifications that respond to the needs of new applications and products. JPEG Innovations workshop held in Tokyo, Japan, on Wednesday 23rd February 2011, is organized to explore such opportunities in new trends in digital photography. On one hand, the workshop will allow its participants to find out about the latest JPEG specifications that could be potentially used for emerging applications. On the other industry experts have been invited to report trends in their products and applications and to identify needs for new digital imaging standards.

JPEG committee invites you to attend this workshop to find out about visions and plans for next generation digital photography products and services, as well as plans by JPEG on timely establishment of international standards that will help accelerate adoption of new products and services by the market, benefiting industry and consumers. Solutions for extensions of existing JPEG formats allowing backward compatibility with legacy systems will be among important issues that will be addressed and discussed during the workshop.

The language of the workshop is English. Participation to the workshop is free of charge, prior registration is however required. Please visit   http://inform.epfl.ch/?form=JPEG_Innovations

The 3D research community is at a potentially revolutionary point. From one side, 3D display technology is at the verge of becoming widespread and reasonably priced, and that includes autostereoscopic displays. From another direction, increases in computational power – including powerful GPUs – has allowed an ever-increasing realism in 3D scene generation. 3D audio in now often tightly integrated with 3D envi- ronments, including 5.1 (and higher) and even 3D soundfield reproduction. Haptic sys- tems are also being tightly integrated within 3D systems. Quality evaluation of 3D sys- tems itself is of great importance, and is also showing fast progress. Finally, new depth cameras, coupled with new 3D analysis and synthesis algorithms is close to enable commercial-quality 3D rendering of real scenes, instead of being restricted to synthetic scenes as in the past.
All these factors together create the “perfect storm”: an environment prone for an explosion of related technology and applications, with a speed of development that will not fit in the (slower) cycle of traditional conferences and journals. In other words, while appropriate venues for presenting research at advanced stages is plentiful, the 3D Multimedia community lacks an appropriate venue for receiving feedback during early or initial stages of the development of radical or potentially disruptive technology.
This is exactly the void that Hot3D tries to fill. After the enormous success of the first Hot3D workshop in Singapore, July 2010, Hot3D is already a premier venue, pro- viding an environment for lively discussion of early-stage, potentially disruptive re- search.


Papers in all areas of Multimedia 3D are solicited. Early stage or preliminary re- sults from potentially disruptive technology is particularly encouraged. Full papers (up to 6 pages) will be published in the ICME proceedings.
Additionally, and maybe most importantly, position papers are solicited for short presentation and discussion of preliminary work or ideas. Submit a proposal of up to 2 pages, with a decision expected up to 3 weeks after submission.
The 1-day workshop will be held on Friday, July 15, and is co-located with ICME, the flagship multimedia conference sponsored by four IEEE societies. The workshop will be a unique opportunity to interact with other researchers working on 3D Multimedia. With an environment designed to facilitate discussion and feedback in early stage re- search, as well as forge new collaboration, this is an event not to be missed.


Submit Regular Paper (up to 6 pages) by: February 20, 2011
Notification of Regular Paper Acceptance: April 10, 2011
Camera‐Ready Paper Due: April 20, 2011

Position Paper (up to 2 pages) Submission: ASAP, up to May 15, 2011

Notification of Position Paper Accept.: within 4 weeks after submission
