Paper Abstract

Directional selective unit, or velocity sensitive unit, is the mechanism in a vision system that responds to motion in a specific direction. This paper analyzes a model for directional selective unit proposed by Barlow and Leveck. This model employsthe inhibitory mechanism. Several parameters of the model are defined and examined. The analysis shows that the range of the response of the unit can be adjusted through the parameters, that the specific values of the parameters are not as important as the relative values of the parameters, and that a family of velocity-sensitive units with different ranges can be used to achieve velocity-specific detection.
