Research Interests

My interests span a wide range of topics in computer vision and graphics, with emphasis on visual surveillance, intelligent user interfaces, and digital photography applications. Specific projects include automated video analysis for surveillance, flash photography for image analysis and rendering, object classification, and face/gesture recognition". In the past five years, I have been working on the award-winning IBM Smart Surveillance System. See the links below:
