| Neurophysiological studies indicate the cortical areas V1, MT, MST and 7a in the primate vision system are involved in the processing of visual motion and are recognized as the motion pathway. A computational model simulating organization of this motion pathway is presented. Attention was incorporated in the model based on the concept of selective tuning. Simple motion patterns such as rotation, expansion, translation or combined motions with two or three patterns can be correctly recognized, localized in the image sequences and attended to serially. By combining four stages of motion processing with an attentional mechanism, our approach yields a biologically plausible model of visual motion processing. |
