Motion Perception Model Based on Competition Process and Spatiotemporal Filter

Abstract

We propose a motion perception model taking into consideration the results of a physiological study that there are different latencies of response to random dot kinematograms (RDKs) motion stimuli and line pattern motion stimuli in middle temporal area (MT). The model is composed of spatiotemporal filters and a competition process. The response latency of MT in this model is longer in response to RDKs than to line patterns. This response behavior has good correspondence with the physiological study. We show that the response of this model is not only dynamic but also robust against noisy motion stimuli.
