Optoelectronic methods of image processing based on local anisotropy features analysis

The paper presents opto-electronic realization of local anisotropy features method. The method is based on the image local neighborhoods Fourier spectrum analyses and their classification. In present realization spectrum is calculated by optical way. The information input into optical systems is made with the help of multichannel acousto-optical modulator. To classify Fourier spectrum kinds, it is convenient to use multisector photoelectric cell.© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering.
