Optical fuzzy image processing based on spatial nonlinear encoding scheme and multiple-imaging technique

An optical system based on polarization- and area-coded scheme and the multiple-imaging technique is proposed for fuzzy image processing. In our scheme, each encoding cell is only composed of one encoding cell so that the resultant pattern is still the image in which there is no space between any two pixel rows. All of the fuzzy logical functions of two images can be implemented in parallel and spatial-invariant by programming the lens-arrays with corresponding modes. In particular, no thresholding device and decoding mask is needed, therefore, our system exhibit a high operation speed and a large information throughout. The experimental results are also given.
