Hybrid optical-digital system of texture recognition with liquid crystal input device

Resumo

The results of experimental research of working hybrid optical-digital image recognition system based on features extracted from Fourier spectra are presented. To form the features an optical Fourier processor with liquid-crystal input device is used. Recognition is carried out with computer (PC) using a neural network algorithm. The possibility of applying the developed system for recognition of the terrain images obtained by aerial photography is shown.
