ABSTRACT:
A digital processor for extracting data from a binary image in which the image is divided into an array of sample areas, each sample area containing an array of binary data spaces. Patterns formed by adjacent data spaces within the sample sample represent local line orientations from which the image characteristics are determined. Sample areas linearly arrayed in the direction in which the image is scanned are simultaneously processed to extract the line orientation information contained therein.
