发明名称 Method and system for recognizing characters.
摘要 <p>A method and system for recognizing an individual unknown character on a document in which, for black pels, one at a time, a vector indicating (56)what is seen from that pel in each of a plurality of directions in terms of white or black pels. That vector is compared (58) to a table created from a large experience, generating a probability for each character in the character set that the vector from the pel on the unknown character is that character. As this process is repeated for other black pels in the unknown character, the probabilities associated with the various pels for each respective character are multiplied together to create a probability for the unknown character. An optional skeletonization (54) of the character prior to recognition assists in the recognition by making the character only one pel width for a stroke, rather than a variable quantity. <IMAGE></p>
