ABSTRACT:
OCR processing involves: acquisition of images from image capturing devices; determination of location/size/style for each character; normalization; smoothing for large corners; smoothing by the deletion of individual protruding and extraneous dots; extraction of features; pattern matching; automatic error correction using a word dictionary; and output of recognition results.
In the present invention, high speed software processes accomplish smoothing large corners and deletion of individual protruding and extraneous dots. In this software processing, the smoothing process is performed by shifting bit rows and using only the logical operators NOT, AND, and OR; not used are the often employed conventional conditional branch commands, such as the "if then else" and "switch" statements. This smoothing method (using only NOT, AND, and OR) contributes to a substantial reduction in the processing speed.
