ABSTRACT:
An image processing method for processing a sequence of motion images in the form of brightness patterns and picked up by a camera. The brightness patterns are applied to a spatiotemporal filtering differentiator having a plurality of initial phases thereof different from each other to obtain a set of local differential values grouped by the initial phases. The differential values are calculated to obtain a set of local brightness gradients.
