Abstract : (1) Developed a theory to explain perceived depth in untextured stereograms which relies on the principle of generic image sampling. (2) Conducted experiments on visual search and visual texture segregation which show that early filter outputs are not accessible to either of these two operations. (3) Discovered a new form of implicit memory which is uniquely shortlasting (approx 30 seconds) and which assists in enabling more speedy popout with repeated trials. (4) Developed a new theory of binocular vision which relies heavily on the importance identification of half-occlusions.
