He has published over 350 research papers and holds four patents in these fields. His Google Scholar citation is over 19200 with an h-index of 66.
Dr. Wu is an IEEE fellow, and served on editorial boards of IEEE Transactions on Image Processing and IEEE Transactions on Multimedia. He is a member of IEEE Multimedia Signal Processing Executive Committee. He won an IS&T/SPIE Best Paper Award, a UWO distinguished research professor award, and a McMaster distinguished engineering professor award.
Xiaolin Wu got his B.Sc. from Wuhan University, China in 1982, and Ph.D. from University of Calgary, Canada in 1988, both in computer science. Dr. Wu started his academic career in 1988, and has since been on the faculty of Western University, New York Polytechnic University (NYU-Poly), and joined McMaster University in 2002, where he is a professor at the Department of Electrical & Computer Engineering, and won a Distinguished Engineering Professor Award.
Also, Dr. Wu has extensive industrial research experiences. He was CTO of Ntec Media GmbH and collaborated with Microsoft, Nokia, Intel, IMAX and Huawei Canada. He held an NSERC senior industrial research chair, and is an IEEE fellow and a member of IEEE Industrial Signal Processing Executive Committee.
- B.Sc. (Wuhan University, China)
- Ph.D.(University of Calgary, Canada)
- Dr. Wu’s CALIC algorithm won the first place in the JPEG lossless image coding competition, and was licensed to companies. The applications of CALIC include medical imaging, satellite imaging, prepress imaging, image archiving, and etc. Wu’s L3 (Layered Low-complexity Lossless) codec for digital cinema won first place in compression performance among seven proposals submitted to MPEG in July 2001. Wu’s fast color quantizer was incorporated into the independent JPEG group’s image compression software package (shareware), and widely used by graphics practitioners.
- His ground-breaking work of temporal psychovisual modulation (TPVM) was featured in MIT Technology Review and in the Exploratory DSP column of IEEE Signal Processing Magazine.
- Dr. Wu developed a family of image restoration algorithms for demosaicing, denoising, superresolution and deblurring.
