Spike to Spike Model and Applications: A biological plausible approach for the motion processing

We propose V1 and MT functional models for biological motion recognition. Our V1 model transforms a video stream into spike trains through local motion detectors. The spike trains are the inputs of a spiking MT network. Each entity in the MT network corresponds to a simplified model of an MT cell. From the spike trains of MT cells a motion map of velocity distribution is built representing a sequence. Biological plausibility of both models is discused in detail in the paper. In order to show the efficiency of these models, the motion maps here obtained are used in the biological motion recognition task. We ran the experiments using two databases Giese and Weizmann, containing two (march, walk) and ten (e.g. march, jump, run) different classes, respectively. The results revealed that the motion map here proposed can be used as a reliable motion representation.
