Speaker: Dr. Wen-Hsiao Peng

Abstract:

The DCT-based image and video coding technique was adopted by the international

standards (ISO JPEG, ITU H.261/264/265/266, ISO MPEG-2/4/H, and many others) for nearly

30 years. Although researchers are still trying to improve its efficiency by fine-tuning its

components and parameters, the basic structure has not changed in the past two decades. The

arrival of deep learning recently spurred a new wave of developments in end-to-end learned

image and video compression. This fast growing research area has attracted more than 100+

publications in the literature, with the state-of-the-art end-to-end learned image compression

showing comparable compression performance to H.266/VVC intra coding in terms of PSNR-

RGB and much better MS-SSIM results. End-to-end learned video coding is also catching up

quickly. Some preliminary studies report comparable PSNR-RGB results to H.265/HEVC or

even H.266/VVC under the low-delay setting. These interesting results have led to intensive

activities in international standards organizations (e.g. JPEG AI) and various Challenges (e.g.

CLIC at CVPR and Grand Challenge on Neural Network-based Video Coding at ISCAS).  In this

talk, I shall overview (1) the recent advances of this area, (2) review some notable end-to-end

learned image/video compression systems, and (3) address recent efforts in creating hardware-

friendly, low-complexity models, and (4) look at the application of end-to-end learned

image/video compression to computer vision tasks, an emerging research area also known as

visual coding for machine perception. The talk will be concluded with potential research

opportunities and an outlook for learned compression systems.

Speaker's bio:

Dr. Wen-Hsiao Peng (M’09-SM’13) received his Ph.D. degree from National Chiao Tung

University (NCTU), Taiwan, in 2005. He was with the Intel Microprocessor Research

Laboratory, USA, from 2000 to 2001, where he was involved in the development of ISO/IEC

MPEG-4 fine granularity scalability. Since 2003, he has actively participated in the ISO/IEC and

ITU-T video coding standardization process and contributed to the development of SVC, HEVC,

and SCC standards. He was a Visiting Scholar with the IBM Thomas J. Watson Research Center,

USA, from 2015 to 2016. He is currently a Professor with the Computer Science Department,

National Yang Ming Chiao Tung University, Taiwan. He has authored over 75+

journal/conference papers and over 60 ISO/IEC and ITU-T standards contributions. His research

interests include learning-based video/image compression, deep/machine learning, multimedia

analytics, and computer vision. Dr. Peng was Chair of the IEEE Circuits and Systems Society

(CASS) Visual Signal Processing (VSPC) Technical Committee from 2020-2022. He was

Technical Program Co-chair for 2021 IEEE VCIP, 2011 IEEE VCIP, 2017 IEEE ISPACS, and

2018 APSIPA ASC; Publication Chair for 2019 IEEE ICIP; Area Chair/Session Chair/Tutorial

Speaker/Special Session Organizer for IEEE ICME, IEEE VCIP, and APSIPA ASC; and

Track/Session Chair and Review Committee Member for IEEE ISCAS. He served as AEiC for

Digital Communications for IEEE JETCAS and Associate Editor for IEEE TCSVT. He was

Lead Guest Editor, Guest Editor and SEB Member for IEEE JETCAS, and Guest Editor for

IEEE TCAS-II. He was Distinguished Lecturer of APSIPA and the IEEE CASS.
