Multiplicative inhibitory velocity detector and multi-velocity motion detection neural network model

Abstract

Motion perception is one of the most important aspects of the biological visual system, from which people get a lot of information of the natural world. In this paper, trying to simulate the neurons in MT (motion area in visual cortex) which respond selectively both in direction and speed, the authors propose a novel multiplicative inhibitory velocity detector (MIVD) model, whose spatiotemporal joint parameterK determines its optimal velocity. Based on the Response Amplitude Disparity (RAD) property of MIVD, two multi-velocity fusion neural networks (a simple one and an active one) are built to detect the velocity of 1-Dimension motion. The experiments show that the active MIVD Neural Network with a feedback fusion method has a relatively better result.
