Research Description:
We use psychophysical techniques, image processing and computer simulations, and current knowledge of visual neurophysiology to try to understand how the visual system processes visual information to result in your perception of the environment. One focus of research is the perception of 3-dimensional shape. Input to the visual system is inherently 2-dimensional, and yet we are able to effortlessly perceive the 3-dimensionality of objects. We have particular interest in understanding how the visual system uses changes in surface texture in the retinal image to accomplish this feat. More recently, we have begun considering how factors such as emotional state and aging affect basic aspects of visual perception.
