AI Technical Summary

Problems solved by technology

However, due to the lack of standardization of handwritten characters, the image segmentation of line characters may cause irreparable recognition errors; at the same time, commonly used statistical methods, projection methods, grid methods and other text recognition methods cannot achieve accurate recognition, and the recognition of these methods is accurate. It is difficult to further increase the rate

Abstract

The invention discloses a character identification method and a character identification system. The character identification method comprises steps of inputting a to-be-identified area image and performing binary processing; extracting stroke characteristics of the to-be-identified area image; extracting relation characteristics between adjacent strokes of all strokes and the corresponding positions; matching radicals; matching characters; and outputting matching results of the to-be-identified area image. The character identification system comprises an image acquiring module, an image processing and character identifying module and a character outputting module. According to the invention, printed and quite neatly handwritten characters can be precisely identified; there are no other restrictions except that the handwritten characters could not be too illegible to read the structure characteristics; and a large number of printed and handwritten manuscripts, tables and bills can be processed at a high speed.

Description

technical field [0001] The invention relates to the field of character recognition, in particular to a character recognition method and system thereof. Background technique [0002] Character recognition technology is an intelligent technology used to automatically input text information into computers, mobile phones and other information processing systems. Text recognition technology is divided into two categories: online recognition and offline recognition. Online recognition refers to inputting handwritten text into the information processing system in real time. Machine recognition technology includes printed character recognition and handwritten character recognition, which is a technology that automatically recognizes and enters characters that have been printed or written on paper or other carriers. [0003] The current automatic recognition technology of printed characters has many products and methods, such as my country's Hanwang, Tsinghua Unigroup, etc. In term...
