New architectures and algorithm for optical pattern recognition using joint transform correlation technique

Abstract EN

Recently, there is increasing interest in using joint transform correlation (JTC) technique for optical pattern recognition.

In this technique, the target and reference images are jointed together in the input plane and no matched filter is required.

In this paper, the JTC is investigated using simulation technique.

A new discrimination decision algorithm is proposed to recognize the correlation output for different object shapes (dissimilar shapes).

Also, new architectures are proposed to overcome the main problems of the conventional JTC.
