Optische Buchstabenerkennung durch Bilden und Auswerten von Matrizen geographischer Merkmale.

摘要

An alphanumeric character is recognized by optically scanning that character, detecting the occurrence of predetermined geographical features in the scanned image, comparing the detected geographical features to a store of particular geographical features which identify respective alphanumeric characters, and identifying the scanned image as the alphanumeric character having those geographical features to which the detected geographical features favorably compare. The aforementioned geographical features comprise lagoons (formed as enclosed areas) and bays (formed as open areas). A matrix representing the juxtapositions of the detected geographical features is generated and compared with stored predetermined matrices which, in turn, represent predetermined characters.
