Stereopsis generated with Julesz Patterns in Spite of Rivalry imposed by Colour Filters

Abstract

IT is well known that binocular fusion of slightly disparate images from the two retinae can produce a sensation of depth. The presence of contours was considered necessary for this effect until Julesz1 used computer generated “random dot stereograms” to show that a depth percept can occur in the absence of contours, and indeed stereopsis can create contours. The binocular fusion of colours (red and green), on the other hand, has been a highly controversial subject since the time of Helmholtz and Hering. Hecht2 produced a yellow fusion with red and green wratten filters but Hurvich and Jameson3 have criticized his interpretation of the fusion.
