linage rotations translations, changes of scale arid distortions require special pattern recognition and classification techniques. One approach is to look for features such as Circular harmonic components that remain invariant under such changes. Tradeoffs involved in invariant pattern recognition will be discussed, with emphasis on optical implementations.
