| Abstract: | Because of the peculiarities in the ID Card:strong disturbances and well -regulated arrangement of information,this paper presents a kind of practical image algorithm for segmenting the characters from the ID Card.In the algorithm,the algorithmic operator of Sobel is used to obtain the local threshold automatically and process the precise segmentation of the characters,combining the way of projection with average -character -center space.The experimental results show that the segmentation effects and orientation accuracy are proved significantly,so the proposed method is effective. |
