主讲嘉宾简介:

Dr Lin Weisi is an active researcher in image processing, perception-based signal modelling and assessment, video compression, and multimedia communication systems. In the said areas, he has published 180+ international journal papers and 230+ international conference papers, 7 patents, 9 book chapters, 2 authored books and 3 edited books, as well as excellent track record in leading and delivering more than 10 major funded projects (with over S$7m research funding). He earned his BSc and MSc from Sun Yat-Sen University, China, and Ph.D from King’s College, University of London. He had been the Lab Head, Visual Processing, 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 awarded Highly Cited Researcher 2019 by Web of Science, and 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.

报告简介(Abstract):

The human is the final appreciator for most visual signals we capture, process and present up to now. As a result of the evolution, the human visual system (HVS) has developed unique characteristics in perceiving the physical world. How to evaluate visual signal quality shapes or at least influences many visual processing algorithms and systems, it is therefore meaningful and beneficial to formulate perceptual quality criteria for visual signals, be they naturally captured or computer generated, in line with the HVS perception.Significant research effort has been made toward modelling the relevant HVS’ mechanisms, and to apply resultant models to various processes in practice.

In this talk, we will first introduce the major problems associated with perceptual visual signal quality metric building, as well as the R&D work in this field. Afterward, we will discuss the related perceptual issues in image retargeting, video coding, computer graphics, target identification, and so on. The talk will also give our opinions for future research directions, and extension to emerging fields, like screen content images, medical imaging, under-water imaging, and so on, as well as exploring into non-visual signals, like audio, smell, touch and taste, based upon substantial recent project experience of the presenter for both academic research industrial deployment.
