Abstract

In nature, it is an important task for animals to detect small targets which move within cluttered background. In recent years, biologists have found that a class of neurons in the lobula complex, called STMDs (small target motion detectors) which have extreme selectivity for small targets moving within visual clutter. At the same time, some researchers assert that lateral inhibition plays an important role in discriminating the motion of the target from the motion of the background, even account for many features of the tuning of higher order visual neurons. Inspired by the finding that complete lateral inhibition can only be seen when the motion of the central region is identical to the motion of the peripheral region, we propose a new lateral inhibition mechanism combined with motion velocity and direction to improve the performance of ESTMD model (elementary small target motion detector). In this paper, we will elaborate on the biological plausibility and functionality of this new lateral inhibition mechanism in small target motion detection.
