Paper Abstract

The spatiotemporal filters modeled after the motion sensitive mechanism found in the biological vision system are analyzed. The analysis is supported by computer simulation of the filter behavior. The spatiotemporal filter under investigation is sensitive to motion in the preferred direction. It also blocks input with uniform intensity and allows only the transition in a leading edge to pass through. A preliminary examination of the frequency domain response suggests a tightly coupled spatiotemporal characteristics between the spatial frequency and the temporal frequency. The similarity and difference of the response between this class of filters and that of the Delayed Difference of Gaussian is also noted.
