My research interest covers a wide range of topics in computer graphics and computer vision. In computer graphics, my interests include animation, environment matting, hardware accelerated graphics, motion editing, physics-based modelling, texture analysis and synthesis, and static and dynamic image-based rendering. Topics in computer vision include edge detection, face detection and recognition, light source estimation, motion estimation, segmentation, 2D and 3D shape analysis, and real-time multiview stereo. I am a senior member of the IEEE and serve on the Editorial Board of the journal Pattern Recognition. I have published over 100 technical papers in international journals and conference proceedings, co-edited one book and served as guest editor of an international journal. In addition, I have served as reviewer to numerous international journals, as committee members to many conferences and review panels. I co-chaired Vision Interface 98.
