Abstract
A method and apparatus for optical character recognition particularly suitable for cursive and scripted text in one or more of several languages follows the tracings of the script and encodes them as a sequence of directional vectors. It reads a preprocessed word or sub-word of interconnected characters as a unit and the characters are accepted in a specific language only if all characters in a unit have been recognized by testing against a first set of language-specific rules without leaving a remainder of any vectors in the unit. If there are vectors remaining unused, it moves a character marker to utilize more or fewer vectors for the current sub-word in order to obtain recognition. If the vectors do not form a character in a first language, the invention consults a second set of language-specific rules and follows similar steps to obtain recognition of one or more characters against the second set of language-specific rules. Also disclosed is a computer-usable medium, for example a magnetic or optical storage diskette, containing code means to execute the invention.
