DETAILED DESCRIPTION Accordingly, it is a general object of the present invention to provide a novel and useful parallel optical processing system wherein the aforementioned problems are eliminated.
Another and more specific object of the present invention is to provide a parallel optical image processing system comprising an image receiving part supplied for detecting an input image, an encoding part for producing an encoded coherent output beam responsive to said image received by the image receiving part, an interconnection part supplied with the encoded coherent optical beam for deflecting the beam in a desired direction, a processing part including optical memory means on which said coherent encoded optical beam is directed, for reading out an encoded image associated with the input image from the optical memory means, threshold means for selecting an encoded associated image which has a predetermined correlation with the input image, feedback means for feeding back the associated image to said interconnection part for changing the deflection of the coherent encoded optical beam, and a decoding part for decoding the associated image.
According to the present invention, advanced image processing such as association of image, adaptation to frequently used images or oblivision of unnecessary image can be achieved.
Further, as a result of the use of the interconnection part which performs three dimensional interconnection of the optical path of the coherent optical beams, crosstalk between the signals carried by the beams is eliminated.
Furthermore, accuracy and reliability of the optical processing is improved as a result of use of the pre-processing part.
Another object of the present invention is to provide a method of encoding an input image according to a basic feature of an object in the input image before it is fed to a parallel optical image processing system.
According to the present invention, requirement for precision of the optical image processing system becomes less stringent and the optical processing performed by the system becomes less sensitive to the disturbances applied to the system
