Projects • Psychophysics and computation of edge detection • Reconstruction of images from contours • Perceptual grouping of contours • Classification of contours in natural images • Perceptual processing of cast and attached shadows • Application: Contour-based image editing • Human attention and eye movements • Application: Attentive panoramic sensing (with Dalsa Inc.) • Perception of surface attitude from texture • Perception of three-dimensional geometry of transparent surfaces • Statistical frameworks for remote-sensed data fusion • Application: Enhanced/Synthetic Vision Systems for aviation (with CAE, UTIAS, NRC FRL) • Computational modeling of human stereopsis (with L. Wilcox, York CVR) York University
