Abstract

In this paper, we investigate human face recognition for facial images involving a high degree of in‐plane and out‐of‐plane 3‐D distortions such as rotation. In the proposed technique, we investigate the problem of invariant face recognition by considering four different classes of images. A small subset of images is used for every class to create a composite image, which represents each class. The proposed technique is implemented by using the fringe‐adjusted filter‐based joint transform correlator (JTC) technique due to its superior performance over alternate JTCs and the feasibility of its implementation in the optical domain. Furthermore, the utilization of the synthetic discriminant function to generate the composite image for enhancing the correlation output is also investigated. Computer simulation results are presented to show the validity of the proposed technique. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 30: 418–423, 2001.
