Neural Basis of Motion Perception

Abstract

Our goal is to understand the neural basis of perception and to test computational models of visual processing. This year we have been pursuing three lines of research. We have been continuing our earlier studies on "motion capture," shape from shading, and stereopsis. Our research suggests that image segmentation based on texture or occlusion can profoundly influence the early visual processing of stereopsis, shape from shading, and motion correspondence. We also have begun to investigate the "filling in" of "artificial scotomas" and of scotomas produced by brain injury. Our goal has been to understand surface interpolation. Finally, we have developed a new psychophysical technique for isolating and studying a fast contour system in human vision, a system that might correspond to the magnocellular pathway of physiologists.
