About Computer Character Recognition Research

With the continuous development of science and technology computer characterrecognition is more and more become one of the important aspects of pattern recognition,the paper file is converted to digital form, and the paper document can be revised or delete,and so on operation, then to process images in digital image processing, complete thecharacter recognition.This article will solve computer problems in character recognition, mainly includestwo aspects. Firstly as to the character images with different degree of inclination for theman-made reason. Put forward a new tilt correction algorithm. The upper edge characterpoint of column of the character is extracted, most of them will fell in a straight line, thatcorrect is formed to be detected straight line, the angle of this line is the inclination angle.Then by template matching accurately,the correction angle is between0to360.and for thetilted text images include handwriting interference, looking for inclined line throughdetecting other character area edge, and also correct it be cross flat vertical state. Secondly,to delete the records and the line marling in the paper document,by using projectionmethod find every nonzero string and even zero string of projection array, and find out theChinese name size and line spacing, and then positioning inter-row part, remove theinter-row handwriting.In matlab system environment, test on images to be detected. And discuss thevarious complicated situations respectively, the results showed that the proposedinclination correction and deleting records methods, have a wide range of application,compared with other algorithms have the very big progress, verify the feasibility andaccuracy of the algorithm.
