Abstract
In the particular embodiment of the invention described in the specification, the identity of an unknown character is determined by comparing matrices representing the unknown character with matrices representing known characters and determining the deviation beween matrices for the unknown and each known character. To obtain the matrices to be compared, a transformation chain is expressed in terms of horizontal, vertical and diagonal vectors, permitting all types of transformation chains to be used. Two-dimensional memory units having superposed shift registers are used in comparing matrices to determine minimum deviation.
