Abstract:
In this paper, we consider the optoelectronic method for constructing a directional field using a rotating slit and an amplitude mask installed in the frequency plane. In order to study the efficiency of the proposed method, it is compared with the digital dispersion method [3] for various model images and field images by means of computer simulation. The efficiency and effectiveness of the developed method was demonstrated in numerical experiments on the recognition of fingerprints using the optical Karhunen-Loève decomposition [4,5].
