Abstract

The present invention relates to a recognition method for pattern matching. The method of the invention comprises: loading an original image; establishing a pattern image; encoding information of image gradient (setting a image division unit, encoding the original image gradient and encoding the pattern image gradient); and searching a subject image. The characteristics of the original image and the pattern image can be extremely simplified by establishing the gray value gradient of the original image and the gray value gradient of the pattern image in horizontal direction and in vertical direction. Because the complicated calculation is extremely simplified and the binary tree method for similarity calculation is used, the calculation speed of the recognition of the invention is extremely increased. Furthermore, the recognition method of the invention combines the second searching method so as to increase the accuracy.
