Optical disk implementation of radial-basis classifiers


We describe an optical disk based system for handwritten character recognition. The recognition scheme is based on a radial basis function approach to pattern classification. The optical system computes the Euclidean distance between an unknown input and 650 stored patterns at a demonstrated rate of 26,000 pattern comparisons per second.
