Rotation invariant real-time optical edge detector

A method for omnidirectional real-time optical edge extraction is proposed. The method consists on the design of a complex filter that is implemented in a Vander Lugt like optical processor. It is emphasized the rotation invariance of the technique, as its equivalence with the Canny edge detector. N...
