Chinese multifont recognition system based on accumulable stroke features

Claim 1

A Chinese multifont recognition system for recognizing multifont and multi-sized Chinese characters; wherein a printed Chinese character is input into a computer via a scanning means and then data corresponding thereto is processed through a recognition process and by means of a character feature learning system, the features of a character are stored in a recognition system so as to expand the storage capacity of Chinese characters and allow multifont Chinese recognition, said system comprising: a host processor to control the execution state of various modules; a scanner, operatively connected to and controlled by said host processor, which can convert data corresponding to the printed Chinese fonts to be recognized into digital data; a scanner interface card disposed between said scanner and host processor for providing a transmission means between said host processor and said scanner; a monitor connected to said host processor for displaying a resultant character pattern; a printer connected to said host processor for printing said resultant character pattern; a character feature learning system, connected to said host processor which includes a scanner driver, a text object detector, a slicer, a feature extractor, an operation processor, and a feature encoder connected together; said learning system instructing the computer to learn a given number of Chinese characters to be recognized, and to read in the features of every character so as to establish a feature data base, which is to be used later for matching an input Chinese character; a character recognition system, connected to said host processor which includes a pre-processor, a feature extractor, a matching recognizer, a matching processor, and a decoder connected together; said character recognition system enabling the character recognized on a paper to be displayed on said monitor or on said printer; and a memory unit connected to said host processor for storing programs and data; wherein said scanner transmits to said host processor, through a scanner interface card, printed Chinese character pattern data, and then said host processor performs the recognition process through said character recognition system or said character feature learning system; and said memory unit stores the features of the characters and programs to be used as reference data so as to match with the features of a given input Chinese character.
