My research has focused on computer vision, especially in the areas of image segmentation, shape reconstruction, and object recognition. In particular, I developed methods for analyzing the effect of lighting on images, as well as multiscale algorithms for segmentation and edge detection and region-based pose estimation techniques. My work deals with the design of algorithms, analysis, and implications to human vision.
