Current Research Program
My research is primarily concerned with the visual perception
of 3-dimensional form from various types of optical information, such
as shading, texture, motion, and binocular disparity. The specific goals
of this research are twofold: First, to identify the formal characteristics
of how an object's 3-dimensional form is perceptually represented; and
second, to discover how these representations are computed from the measurable
properties of visual images. In addressing these issues we attempt to
develop specific computational models of how image structure could be
perceptually analyzed, and to empirically test the validity of those models
for actual human observers.
