Abstract
A new synthetic discriminant-function-based amplitude modulated phase-only filtering technique is proposed for scale invariant pattern recognition. Th is technique has been found to yield improved correlation output when compa red with the alternate techniques. The proposed technique is inherently sui table for optical implementation using the currently available spatial ligh t modulators. Simulation results confirm the effectiveness of the proposed technique. (C) 2000 Elsevier Science Ltd. All rights reserved.
