JPEG format is today a synonymous of modern digital imaging, and one of the most popular and widely used standards in recent history. Images created in the legacy JPEG format now exceed several billion per day in their number, and most of us can count a couple, if not more JPEG codecs in devices we regularly use in our daily lives; in our mobile phones, in our computers, in our tablets, and of course in our cameras. JPEG ecosystem is strong and continues an exponential growth for the foreseeable future. Likewise, JPEG 2000 has been successfully deployed in a number of professional applications ranging from digital cinema to broadcasting, as well as in archival, and in medical imaging.
This talk will start with a quick overview of a recently completely JPEG XT which aims at extending the legacy JPEG format in a backward compatible manner to allow for new features such as HDR and WCG imaging, lossless and alpha channel coding. We will also briefly discuss some of the potential extensions of JPEG XT towards, privacy protection and security, animated content, as well as 360 and VR photography.
The talk will then concentrate on JPEG XS, a new initiative for light weight and low latency image compression system. After motivating the needs for such a standard by means of several illustrative examples, we will analyze potential solutions which could eventually fulfill low latency and lightweight compression, and over view some of the challenges both in design of such codecs and in their assessments.
The talk will end with an overview of an emerging standardization effort called JPEG PLENO which addresses solutions for compression of light field, point cloud and holography, and the latest status of JPEG activities in these areas.
Biography: Prof. Touradj EBRAHIMI (EPFL) received his M.Sc. and Ph.D., both in Electrical Engineering, from the Swiss Federal Institute of Technology (EPFL), Lausanne, Switzerland, in 1989 and 1992 respectively. In 1993, he was a research engineer at the Corporate Research Laboratories of Sony Corporation in Tokyo, where he conducted research on advanced video compression techniques for storage applications. In 1994, he served as a research consultant at AT&T Bell Laboratories working on very low bitrate video coding. He is currently Professor at EPFL heading its Multimedia Signal Processing Group. He was also adjunct Professor with the Center of Quantifiable Quality of Service at Norwegian University of Science and Technology (NTNU) from 2008 to 2012. He is currently the Convenor of JPEG (Joint Photographic Experts Group) standardization committee. Prof. Ebrahimi has been the recipient of various distinctions and awards, such as the IEEE and Swiss national ASE award, the SNF-PROFILE grant for advanced researchers, Four ISO-Certificates for key contributions to MPEG-4 and JPEG 2000, and the best paper award of IEEE Trans. on Consumer Electronics . He became a Fellow of the international society for optical engineering (SPIE) in 2003. Prof. Ebrahimi has initiated more than two-dozen National, European and International cooperation projects with leading companies and research institutes around the world. He is also the head of the Swiss delegation to MPEG, JPEG and SC29, and acts as the Chairman of Advisory Group on Management in SC29. He is a co-founder of Genista SA, a high-tech start-up company in the field of multimedia quality metrics. In 2002, he founded Emitall SA, start-up active in the area of media security and surveillance. In 2005, he founded EMITALL Surveillance SA, a start-up active in the field of privacy and protection. He is or has been associate Editor with various IEEE, SPIE, and EURASIP journals, such as IEEE Signal Processing Magazine, IEEE Trans. on Image Processing, IEEE Trans. on Multimedia, EURASIP Image Communication Journal, EURASIP Journal of Applied Signal Processing, SPIE Optical Engineering Magazine. Prof. Ebrahimi is a member of Scientific Advisory Board of various start-up and established companies in the general field of Information Technology. He has served as Scientific Expert and Evaluator for Research Funding Agencies such as those of European Commission, The Greek Ministry of Development, The Austrian National Foundation for Scientific Research, The Portuguese Science Foundation, as well as a number of Venture Capital Companies active in the field of Information Technologies and Communication Systems. His research interests include still, moving, and 3D image processing and coding, visual information security (rights protection, watermarking, authentication, data integrity, steganography), new media, and human computer interfaces (smart vision, brain computer interface).
He is the author or the co-author of more than 200 research publications, and holds 14 patents. Prof. Ebrahimi is a member of IEEE, SPIE, ACM and IS&T.
