Oscar C. Au received his Bachelor of Science degree from Univ. of Toronto, his Master of Arts and Ph.D. from Princeton University in 1988 and 1991 respectively. After being a postdoctoral researcher in Princeton for one year, he joined the Hong Kong University of Science and Technology (HKUST). He was a Professor of Electronic and Computer Engineering, Director of Multimedia Technology Research Center (MTrec), and Director of the Computer Engineering (CPEG) Program in HKUST. He is now a patent engineer in LegalForce.

His main research contributions are on video and image coding and processing, watermarking and light weight encryption, speech and audio processing. Research topics include fast motion estimation for MPEG-1/2/4, H.261/3/4 and AVS, optimal and fast sub-optimal rate control, mode decision, transcoding, denoising, deinterlacing, post-processing, multi-view coding, view interpolation, depth estimation, 3DTV, scalable video coding, distributed video coding, subpixel rendering, JPEG/JPEG2000, HDR imaging, compressive sensing, halftone image data hiding, GPU-processing, software-hardware co-design, etc.

He has published 70+ technical journal papers, 380+ conference papers, and 70+ contributions to international standards. His fast motion estimation algorithms were accepted into the ISO/IEC 14496-7 MPEG-4 international video coding standard and the China AVS-M standard. His light-weight encryption and error resilience algorithms are accepted into the China AVS standard. He was Chair of Screen Content Coding AdHoc Group in the JCTVC for the ITU-T H.265 HEVC video coding standard. He has 30+ granted patents and is applying for 60+ more on his signal processing techniques. He has performed forensic investigation and stood as an expert witness in the Hong Kong courts many times.

Dr. Au is a Fellow of the Institute of Electrical and Electronic Engineering (IEEE) and is a Board 0f Governor member of the Asia Pacific Signal and Information Processing Association (APSIPA). He is/was Associate Editors of IEEE Trans. On Circuits and Systems for Video Technology (TCSVT), IEEE Trans. on Image Processing (TIP), and IEEE Trans. on Circuits and Systems, Part 1 (TCAS1). He is on the Editorial Boards of Journal of Visual Communication and Image Representation (JVCIR), Journal of Signal Processing Systems (JSPS), APSIPA Trans. On Signal and Information Processing (TSIP), Journal of Multimedia (JMM), and Journal of Franklin Institute (JFI).

He is/was Chair of IEEE CAS Technical Committee on Multimedia Systems and Applications (MSATC), Chair of SP TC on Multimedia Signal Processing (MMSP), and Chair of APSIPA TC on Image, Video and Multimedia (IVM). He is a member of CAS TC on Video Signal Processing and Communications (VSPC), CAS TC on Digital Signal Processing (DSP), SP TC on Image, Video and Multidimensional Signal Processing (IVMSP), SP TC on Information Forensics and Security (IFS), and ComSoc TC on Multimedia Communications (MMTC).

He served on the Steering Committee of IEEE Trans. On Multimedia (TMM), and IEEE Int. Conf. of Multimedia and Expo (ICME). He also served on the organizing committee of IEEE Int. Symposium on Circuits and Systems (ISCAS) in 1997, IEEE Int. Conf. On Acoustics, Speech and Signal Processing (ICASSP) in 2003, the ISO/IEC MPEG 71st Meeting in 2005, Int. Conf. on Image Processing (ICIP) in 2010, and other conferences. He was General Chair of Pacific-Rim Conference on Multimedia (PCM) in 2007, IEEE Int. Conf. on Multimedia and Expo (ICME) in 2010 and the International Packet Video Workshop (PV) in 2010. He won best paper awards in SiPS 2007, PCM 2007 and MMSP 2012. He is an IEEE Distinguished Lecturer (DLP) in 2009 and 2010, and has served as keynote speaker on multiple occasions.
