Weisi Lin graduated from Sun Yat-Sen (Zhongshan) University, China with B.Sc in Electronics and M.Sc in Digital Signal Processing, respectively, and from King’s College, London University, UK with Ph.D in Computer Vision. He taught and researched in Sun Yat-Sen University, Shantou University (China), Bath University (UK), National University of Singapore, Institute of Microelectronics (Singapore), and Institute for Infocomm Research (Singapore). He has been the project leader of 10+ successfully delivered projects in digital multimedia technology development. He also served as the Lab Head, Visual Processing, and then the Acting Department Manager, Media Processing, in Institute for Infocomm Research. He holds 16 patents, wrote 9 book chapters, edited 3 books, authored 2 books, published over 400 refereed papers in international journals and conferences, and made more than ten contributions to international standardization. He believes that good theory is practical so has kept a balance of academic research and industrial deployment throughout his working life.

US 2014/0301462 A1: Lossless Image and Video Compression (2017)
Abstract: A method is provided for encoding an intra predicted residual block of an image for use in image or video compression. The intra predicted residual block is associated with an intra prediction coding mode. The method includes generating a set of residual error blocks including residual data with different statistical characteristics from the residual data in the intra predicted residual block. Each of the residual error blocks is scanned and entropy coded to produce a first set of bit streams. The lengths of each of the first set of bit streams are recorded. The intra predicted residual block is also scanned and entropy coded to produce a second bit stream. The length of the second bit stream is recorded. Selecting the minimum length bit stream from the first set of bit streams and the second bit stream as the output coded bit stream of the intra predicted residual block.

US 2014/0169662 A1: Image Retargeting Quality Assessment (2015)
Abstract: A method of performing an image retargeting quality assessment comprising comparing an original image and a retargeted image in a frequency domain, wherein the retargeted image is obtained by performing a retargeting algorithm on the original image. The disclosure also includes an apparatus comprising a processor configured to perform an image retargeting quality assessment, and compare an original image and a retargeted image in a spatial domain, wherein the retargeted image is obtained by performing a retargeting algorithm on the original image, and wherein comparing the original image and the retargeted image in the spatial domain comprises comparing the original image and the retargeted image to determine an amount of shape distortion between the images.
