Event Details

I will discuss some of our work on modeling stereoscopic depth perception based on physiological properties of binocular cells in the visual cortex.  I will show that binocular disparity maps can be effectively computed from stereograms with a population of complex cells, without explicit feature matching.  I will then describe a unified theory for understanding depth effects of both horizontal and vertical disparities.  I will present our psychophysical data for testing two key predictions of the theory.  Finally, I will show that our stereo model can be naturally combined with the motion-energy model to explain a family of Pulfrich depth illusions, and will address some recent criticisms of this explanation.
