Biologically inspired local motion detector architecture

A new directionally sensitive motion detection system is proposed that is capable of detecting local motion without any significant preprocessing. It has a delay-and-compare structure like that of the Reichardt detector but uses as its basic building block the shunting inhibition neural model. It is therefore called the local inhibitory motion detector. Furthermore, an array of such detectors exhibits adaptive responses akin to those observed in motion-sensitive biological neurons.
