Many Renaissance master painters attempted to achieve realism in their paintings with much success. Nowadays, we are repeating their footsteps in computer graphics except that we use a computer instead of a paintbrush. Indeed, realism or photo-realism has been a goal in computer graphics research in the last few decades. Many techniques have been developed, e.g. ray tracing and radiosity. It is well known that an accurate representation of a scene requires complex geometric models as well as physically correct material properties of objects in the scene. One major problem is that the computational cost increases with the complexity of the scene. Additionally, to be able to mix synthetic objects with a real scene, we also need accurate information of the distribution of light sources. Each of the above topics presents challenges and requires different solution techniques. One very promising approach is the image-based techniques. In this talk, I will present results obtained by our group in addressing the above issues as well as the challenges that remain in achieving realism.
BIOGRAPHY:
Dr. Yang received his B.Sc. (first honours) from the University of Hong Kong, M.Sc. from Simon Fraser University, and M.S.E.E. and Ph.D. from the University of Pittsburgh. Dr. Yang's research interests cover a wide spectrum of topics in computer graphics and computer vision, which include 2D and 3D shape analysis; edge detection; segmentation; motion analysis; ultrasound image processing; colour image processing; physics-based modelling and animation; human body motion analysis and animation; rendering of realistic imagery; multi-baseline stereo; image-based modeling and rendering; texture analysis and synthesis; and multiview vision and rendering. He was on the faculty in the Department of Computer Science, University of Saskatchewan from 1983 to 2001; was promoted to full professor in 1991 and served as Graduate Chair from 1999-2001. Since 2001, he is a professor in the Department of Computing Science, University of Alberta. He was Associate Chair (Graduate Studies) in the same department from 2003 to 2005. He is a senior member of the IEEE and serves as Associate Editor for the journal Pattern Recognition. He has published over 80 papers in international journals and conference proceedings. He co-chaired Vision Interface 98 and was on the program committee of Vision Interface 2000, VRST 2001, Pacific Graphics 2003 and CAD/Graphics 2005.
