Motion Interpretation of Trochoid Paths with a Rotational Motion Sensitive Network and Attention Mechanism

This paper present a simulation of motion interpretation of trochoid path generated by a single point on a rotating disc translating in the frontoparallel plane of the visual eld. The process involves two mechanisms. First, the extraction of relative motion in a group motion and second the presence an attention mechanism. Speci cally, the paper present neural simulation results for cycloidal motion extraction. We construct our neural network according to the directional and speed sensitivity pro le observed in neurophysiological data available. The intermeditate interpretation of rotational motion is then constructed. We then show that without an attention mechanism the perception is insu cient to elicit a rotational perception. However, with an attention mechanism the rotating wheel is perceived readily.
