In order to improving the ability of objective recognition with optical joint transform correlator (JTC). A novel algorithm for the correlator output image is proposed. The experimental results show that this algorithm can accurately identify the object with rotated range form -4° to +10° and scale range from 70% to 140%, improve tremendously the distortion unchanged tolerance.
