Paper Abstract

The submitted paper is devoted to a description of relevant experience with an implementation of optical JTC (Joint Transform Correlation) processing technique in two selected security applications - fingerprint and face recognition. It summarizes a long time testing of the above mentioned technique under various conditions and effects appearing frequently in real applications. The JTC configuration is a very well known optical scheme for a 2D correlation calculation that is widely used for identification and classification purposes in image databases. The optical hardware provides a fast and massively parallel performance with large computational power required by the 2D image correlation. The performance of a real setup exhibits some shortcomings caused by expected initial distortions and artifacts in the image. The numerous distortions have been tested such as zooming, deformation etc. relevant for real samples of fingerprints and faces and some results are summarized here and presented in comprehensive diagrams.
