Problems solved by technology

[0004] However, traditional Chinese character recognition is usually based on artificial experience to extract features, which does not have certain noise anti-interference ability
Therefore, when the noise interference is large, the recognition rate of Chinese characters will be low

Abstract

The invention relates to a character recognition method and device. The character recognition method includes the following steps that: a convolutional neural network is adopted to perform feature extraction on a character image to be recognized, so that a character feature value is obtained; and an MQDF classifier is adopted to perform classification processing on the character feature value, so that a character corresponding to the character image to be recognized can be obtained. According to the character recognition method and device provided by the embodiments of the invention, the convolutional neural network is adopted to perform feature extraction on the character image to be recognized, so that the obtained character feature value is more precise and has high anti-interference ability, and therefore, the accuracy rate of the character recognized by the MQDF classifier according to the character feature value is high.

Description

technical field [0001] The present disclosure relates to the technical field of pattern recognition, in particular to a character recognition method and device. Background technique [0002] The research purpose of pattern recognition technology is to construct a machine system that can replace humans to complete the tasks of classification and identification, and then carry out automatic information processing, according to the recognition mechanism of the human brain and through computer simulation. The development of Chinese character recognition in pattern recognition has a certain history. For traditional Chinese character recognition, if there is little noise interference, the recognition rate can reach more than 95%. The most typical application is ID card recognition and business card recognition. [0003] The traditional Chinese character recognition method is based on traditional feature extraction, and then uses an improved secondary classification function (Modi...
