| Abstract(in English) | To improve the recognition rate in statistical character recognition,it is used generally to increase the size of the feature vector by the refinement of spatial division.However,in the simple stroke images like alphanumeric characters,the normality of the distribution for there feature vectors reduces as the number of the border points in each subregion decreases,and that the recognition rate can′t be improved.In this report we intr oduce a method using increased direction indices derived from the gray level gradients in the character image.In a computer experiment,we obtained a good recognition rate(correct:99.21%, error:0.79%)with handwritten 3-digit ZIP codes from Second IPTP character Recognition Competition. |
