Embodiment Construction

[0020] In the process of character recognition, font information is the key to realize a high-performance recognition system. At the same time, font information is also an important basis for layout analysis, layout understanding and layout recovery. First of all, the text recognition system must not only accurately recognize the characters of the text, but also be able to restore the original layout format, and the restoration of the layout format includes the restoration of the font information. Second, since characters in different parts of the layout often use different fonts, such as titles, abstracts, and body text, font information can assist layout analysis and understanding. Third, due to the simplicity of single-body character recognition compared to multi-body character recognition, single-body character recognition systems have higher recognition rates and better robustness than multi-body character recognition systems. If the font information of the Chinese chara...

Abstract

A character identification method based on character font prediction includes carrying out character style analysis on file to be identified and carrying out character division on analyzed out character region to obtain image data of single character, carrying out single font identification in sequence on character image data of character region according to reference value sequence of font statistics.

Description

technical field [0001] The invention belongs to the fields of pattern recognition, artificial intelligence and Chinese information processing, in particular to a character recognition method based on font prediction. Background technique [0002] Recognition of printed Chinese characters is the mainstream of Chinese character recognition technology. Among them, the multi-font multi-symbol printing font recognition system has high adaptability and anti-interference ability, but the recognition rate is low. On the contrary, the single-font Chinese character recognition system has low adaptability and anti-interference ability, but high recognition rate. [0003] For multi-font and multi-symbol print recognition, there are mainly two recognition methods currently used. [0004] One is multi-feature extraction and multi-classification. This method mainly uses the features of Chinese characters to divide the recognition process into two levels: coarse classification and fine c...
