Translation, Rotation, Scale and Aspect Invariant Matched Filter and Scene Combination.

Abstract

An interesting pattern has been discovered, which when used as the input scene to a Vander Lugt type correlator, possesses almost complete invariance to the usual problems associated with pattern recognition. The scene may be translated, rotated, scaled, or tilted without total loss of the correlation signal. This, of course, is a specialized scene, but interesting applications for such a pattern do exist. (Author)
