dmax for stereopsis and motion in random dot displays.

摘要: The upper displacement limit for motion was compared with the disparity stereopsis using two-frame random dot kinematograms or briefly presented stereograms. dmax (the disparity/displacement at which subjects make 20% errors in a forced-choice paradigm) found to be very similar and stereo all densities, fall increasing density (0.006% two dots 50%) according power law (exponent −0.2). If is limited by spacing of false targets, this pattern results suggests that spatial primitives input correspondence process may derived from multiple scales. A model MIRAGE centroids provides good fit data.
