Overview
My research focuses on multimedia communications and image/video processing. The overall goal of my research is to find schemes to improve digital media (e.g., image, audio, video) communication across different types of networks. In particular, my research focuses on pre-processing, source coding (compression), quality assessment and post-processing of digital media. Thanks to the rapid growth of technology in the past two decades and popularization of digital devices, multimedia has become an inseparable part of our daily lives. People can access digital media via different devices ranging from televisions and computers to mobile devices. The applications of multimedia communications include: entertainment (TV, cinema), education, biomedicine and education to name a few.

Dr. Shahram Shirani received his Bachelor of Engineering in Electrical Engineering from Isfahan University of Technology, Iran, and his Master of Science (with honours) in Biomedical Engineering from the Amirkabir University of Technology, Iran and his Ph.D. in Electrical Engineering from the University of British Columbia, Canada in 1989, 1994 and 2000, respectively. Since July 2000, he has been with the department of Electrical and Computer Engineering, McMaster University where currently he is a professor and holds Wilson/Bell Canada chair in Data Communications. His research is mainly focused on image and video processing, multimedia compression and communications, medical image processing and hardware architectures for image and video processing. He was an Associate Editor and member of the editorial board for IEEE Transactions on Multimedia and an Associate Editor and is a member of the editorial board for IEEE Transactions on Circuits and Systems for Video Technology.

3 unit(s) Central to computer vision are the mathematical models governing image formation and methods for processing and recovering information based on the model and the image data. In this course we concentrate on statistical and geometrical models of visual data. Assuming a statistical model for the visual data, we talk about learning and inference. We cover modeling of the data densities, regression and classification methods and how we can use graphical models (e.g., Vitterbi, belief propagation) to solve learning and inference problems. In the other half of the course we take a geometrical approach to image formation and look at problems such as image blending and stitching and 3D reconstruction.
