Abstract:

The articles enclosed with this report describe work related to five aspects of visual information processing 1 Continuing studies of two separate motion-computation systems in human vision and the derivation of the functional properties of each. 2 The investigation of three dimensional structure derived from two dimensional visual inputs. 3 A potent form of spatial contrast-gain- control was discovered and found to be not only frequency selective but also orientation specific. This form of local gain control may exemplify a universal form of neural normalization. 4 Studies of human pattern recognition of familiar shapes such as letters show that its statistical efficiency approaches an incredible 50 of the ideal detectors efficiency when the pattern is spatially bandpass filtered in a band whose wavelength is of the same order as the pattern itself. 5 Studies of real and simulated saccadic eye movements in which the same sequence of images that is produced on the retina during saccadic eye movements is artificially produced on a stationary retina.
