Abstract

A model is presented, consonant with current views regarding the neurophysiology and psychophysics of motion perception, that combines the outputs of a set of motion-sensitive spatiotemporal filters to estimate the velocity of a moving texture — without first computing component (or normal) velocity. A parallel implementation of the model encodes velocity as the peak in a distribution of velocity-sensitive units that behave much like cells of the middle temporal (MT) area of the primate brain.
