Contour attributes of a character image to be automatically recognized are extracted directly from the image stored in run-length form by simple logical operations comparing run lengths from adjacent scan lines. Elemental attributes thus collected can be used directly for recognition or can be logically combined into shape classifications of greater significance. The images of characters to be recognized are segmented from other image data, normalized in size to fit a standard frame, and converted into an array of horizontal run lengths.
