Paper Abstract

The difference-squared error algorithm provides an effective means for discriminating between objects of interest and structured background features. This paper briefly discusses the advantages of this algorithm over conventional correlation based recognition techniques. The output of a real-time acousto-optic processor which computes the difference-squared error between an input data stream and a reference function is presented. The output of this acousto-optic implementation is then compared to the desired theoretical results. Finally, future applications of this architecture for real-time two-dimensional pattern recognition is discussed.
