Research Description

Professor Siddiqi's research focuses on visual shape analysis for computer vision, drawing on techniques from singularity theory, partial differential equations and graph theory. He is also interested in the application of curve and surface evolution techniques to problems in image processing and medical image analysis, as well as in the psychophysics of shape perception.
