Abstract
A 2D correlation of images is one of very efficient methods used in both identification and classification area of image processing. Numerical evaluation of 2D is computationally highly demanding and therefore the optical methods are interested because of parallel and fast performance. The JTC (Joint Fourier Transform) is a well known optical technique for an evaluation of 2D correlation. The paper deals with practical problems of JTC technique implementation-- available SLMs, image sensors and modifications of original optical system. Finally some possible applications in transport are discussed.
