ABSTRACT:
A character recognition system identifies characters including hand written characters with a high degree of accuracy by use of spiral view codes for pels in the scanned character image. The spiral view codes are developed by comparing stroke length or distance to a remote stroke from a first radial view from a character pel to stroke length or distance to a remote stroke from a counterclockwise adjacent view for the same character pel. These spiral view codes are collected into a spiral view pattern for each character pel. The spiral view patterns for a character are accumulated to form a character vector. The character vector is analyzed by a linear decision network or a neural network.
