Please join us as we welcome, Professor Touradj Ebrahimi, EPFL, Head of Multimedia Signal Processing Group, and Convenor (Chairman) of JPEG Standardization Committee on Tuesday, October, 29th, 2019, 6:30PM-8:30PM, at swissnex San Francisco, Pier 17 (map).

Touradj EBRAHIMI is Professor at EPFL heading its Multimedia Signal Processing Group. He is also the Convenor of JPEG 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, several ISO-Certificates for key contributions to standardization, the best paper award of IEEE Trans. on Consumer Electronics and the first IEEE Star Innovator award in multimedia. 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 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 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).

Presentation Abstract
Image contents often represent a substantial volume of data. In most cases, there is a statistical redundancy among samples of such data that if appropriately modelled, can reduce their volume. Also, as the vast majority of image contents are destined to be consumed by human subjects, further compression can be obtained by taking into account the properties of the human visual system.  Practical considerations such as complexity, memory requirements, delay, progressiveness, backward compatibility, lossy or lossless transcoding, error resiliency, etc. often play an important role when designing and deploying useful image and video compression technologies.

In this talk, we start with an overview of the design choices that led to the popular JPEG and JPEG 2000 image compression standards with emphasis on their strengths and weaknesses. We then discuss more recent image compression formats such as JPEG XR, JPEG XS, JPEG XT, and JPEG XL, along with motivations that led to their design and the added values they bring. The recent JPEG Pleno compression standard that allows efficient compression of new imaging modalities such as light field, point cloud, and holography is then discussed. Last but not least, the role of machine learning and in particular the impact of the paradigm shift from humans as consumers of images and video, to machines and computer vision systems, will be discussed, and emerging ideas on how to design image compression based on deep learning will be presented.
