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 recognition method and a system thereof. The steps of the character recognition method include inputting an image of a region to be recognized and performing binarization processing; extracting stroke features of the region to be recognized; Part matching; word matching; output the word matching result of the area to be recognized. The character recognition system includes an image acquisition module, an image processing and character recognition module and a character output module. The invention can accurately identify printed and neat handwritten characters, and has no other restrictions except that the handwritten characters are not so scribbled that the text structure features cannot be seen, and can process printed and handwritten manuscripts and forms at high speed and in large quantities. and bills etc.

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...
