Abstract

The recognition of patterns is accomplished through boundary tracing and subsequent storage of encoded range testable data commensurate with the occurrence, interrelationship and orientation of geometric features on the pattern boundaries. The encoded data is compared with generalized prototypes which define the geometric shape of all probable permutations of all possible patterns to be recognized, a match between the encoded data and a prototype constituting identification of the pattern.
