Paper Abstract

A report on the effects of quantizing stereo pairs computed for stereopsis is presented. Two methods for quantization of color images -- the octree method, which is elegant and fast, and the MaxMin method, which was designed for pseudo-random dithering -- are compared. Their application to stereo pairs, which have been computed using true color (24 bit), can cause anomalies in the resulting stereo image such as loss of depth, contradictory features leading to binocular rivalry, image discontinuities, and loss of definition. Techniques for image sampling to decrease processing time and color lookup table construction to minimize the anomalies are also discussed. A solution for quantizing stereo animations is suggested.
