Handwriting digit recognition based on extension engineering

The complicated training algorithm is needed in the traditional handwriting digits recognition, the complexity of algorithm is very high, and the expansibility to huge database is small. In this paper, the handwriting digit is recognized by means of the extension engineering. The classical domains and the extensional domains of handwriting digit character are constructed. The integrated correlative degrees of the measuring digits and 10 basic digits are calculated and handwriting digits are classified and recognized. According to the calculated correlative degrees and the recognized results, extension engineering is an effective method to handwriting digit recognition.
