Research

How does the brain achieve visual perception of 3D space? My research aims to provide some answers by identifying, elucidating and modelling visual perceptual processes involved. This work uses psychophysical methods to examine visual perception in human subjects. Broadly, my research examines how the visual system uses visual cues to determine the 3D location and shape of surfaces in the world. A particular interest is the question of how disparity information provided by two eyes’ images is used to generate stereoscopic depth perception.
