Natural scenes in our visual world are filled with objects delineated from their backgrounds not only by simple changes in luminance or colour, but also by differences in contrast, texture or motion. Dr. Baker is interested in how early visual processing detects and uses these rich cues to provide a robust perception of "figure-ground" relationships in the real world. Towards this end, he employs a variety of approaches in both humans and animals, including psychophysics, brain imaging, single unit neurophysiology, and computational modeling.Neurophysiology, psychophysics, vision, motion perception, visual cortex, mathematical models, optical imaging
