Paper Abstract

We present a new paradigm for studying motion perception. This approach is based on a class of stimuli that we devised for testing the relative strength of stimulus attributes (luminance, color, spatial frequency, orientation, binocular disparity, etc.) in eliciting motion perception by correspondence matching. In this class of stimuli, different attributes are matched simultaneously in the spatio-temporal domain in a systematic, algorithmic manner which allows each attribute to produce motion in an arbitrary direction (if, of course, it is a token for movement perception), independently of the other attributes. This results in animation sequences in which many different motion paths may co-exist, each path due to a different attribute. Such an arrangement allows a direct comparison of the strength of attributes in eliciting movement. Results from psychophysical experiments based on our paradigm can be used to develop complex motion detection models for machine vision systems which attempt to approximate human performance. Similar methods are discussed for studying stereopsis mechanisms.
