Abstract

The model of the real-time scale-rotation invariant joint transform correlator (JTC) was proposed. The pattern recognition algorithm realized by this correlator was developed. The information-dynamic characteristics of the JTC's input device contained the TV-tube and the joined liquid crystal spatial light modulator are studied. The experimental setup of the JTC for binary image recognition was created. The optimum working modes of the constructed correlator were found. The possibilities of the JTC's experimental setup for the finger-print pattern recognition were investigated.
