A Digital Character Recognition Algorithm Based on the Template Weighted Match Degree

Template matching algorithm has the characteristics of high speed and real-time. This paper introduces template matching algorithm, and put forward an improved template matching algorithm which based on the weighted matching degree. After the completion of the pre-processing of input characters, the algorithm uses the moving match of the standard character template with respect to image character template. It uses a method of weighted matching degree. This algorithm can provide a higher matching rate of image character, and overcome the fallacious recognition produced by traditional calculation method. It not only guarantees the accurate recognition rate of general character, but also effectively avoids the influence of adherent noise and partial distortion, which greatly impacts the recognition rate of the character.
