Discrimination of Locomotion Direction at Different Speeds: A Comparison between Macaque Monkeys and Algorithms

Models for visual motion perception exist since some time in neurophysiology as well as computer vision. In this paper, we present a comparison between a behavioral study performed with macaque monkeys and the output of a computational model. The tasks include the discrimination between left and right walking directions and forward vs. backward walking. The goal is to measure generalization performance over different walking and running speeds. We show in which cases the results match, and discuss and interpret differences.
