Abstract:
There are several good reasons to make machines that process visual signals (image, video, graphics, animation, screen content, and their combinations) perceive as humans do: artificial intelligence (AI) aims to mimic human capabilities in problem solving; most visual signals (be they naturally captured or computer-generated) we manipulate are for human consumption and uses; human perception is effective and efficient so machines that emulate human functioning have technical advantages; there is an increasing need for harmonious human-machine interaction (in the near future we may have to deal with robots acting as salespersons, colleagues or care-givers). So far, we have been able to build machines that perform significantly better and quicker than our body parts like arms and legs. However, when it comes to modeling human perception, the odyssey proves to be much more difficult. In this seminar, the major problems and research progress in perceptual signal processing will be introduced. The basic computational models (e.g., visual attention, just-noticeable difference, and perceptual signal quality metrics) will be discussed. Afterward, different perceptually-inspired signal processing techniques will be presented. Much of the materials will be drawn upon the presenter’s substantial experience in related academic and industrial projects. The last part of the seminar discusses future research and development possibilities, including those enabled by the emerging big data, cloud media, AI, and VR/AR.

He earned his Ph.D from King’s College, University of London. He had been the Lab Head, Visual Processing, in Institute for Infocomm Research (I2R). He is a Professor in School of Computer Science and Engineering, Nanyang Technological University, where he served as the Associate Chair (Graduate Studies) in 2013-2014.
He is a Fellow of IEEE and IET, and an Honorary Fellow of Singapore Institute of Engineering Technologists. He has been elected as a Distinguished Lecturer in both IEEE Circuits and Systems Society (2016-17) and Asia-Pacific Signal and Information Processing Association (2012-13), and given keynote/invited/tutorial/panel talks to 20+ international conferences during the past 10 years. He has been an Associate Editor for IEEE Trans. on Image Processing, IEEE Trans. on Circuits and Systems for Video Technology, IEEE Trans. on Multimedia, IEEE Signal Processing Letters, Quality and User Experience, and Journal of Visual Communication and Image Representation. He was also the Guest Editor for 7 special issues in international journals, and chaired the IEEE MMTC QoE Interest Group (2012-2014); he has been a Technical Program Chair for IEEE Int’l Conf. Multimedia and Expo (ICME 2013), International Workshop on Quality of Multimedia Experience (QoMEX 2014), International Packet Video Workshop (PV 2015), Pacific-Rim Conf. on Multimedia (PCM 2012) and IEEE Visual Communications and Image Processing (VCIP 2017). He believes that good theory is practical, and has delivered 10 major systems and modules for industrial deployment with the technology developed.
