Problems solved by technology

[0016] The technical problem solved by the present invention is to provide a font recognition method and system to solve the failure, misjudgment, or poor robustness that occurs when the English recognition is stuck, which leads to the character recognition rate and character recognition rate in the subsequent processing process. The problem of slowing down the recognition speed

Embodiment Construction

[0092] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

[0093] Aiming at the deficiency of judging sticky English in the prior art, the embodiment of the present invention is obtained by horizontally projecting characters whose width exceeds a certain threshold (possibly sticky English, a single Chinese character, or sticky Chinese), and then analyzing The projected curve and the geometric properties of the entire line judge the attributes of the characters. Thereby, the recognition efficiency is improved, and the more fonts are stuck together, the higher the reliability of the recognition is, thereby improving the recognition rate of OCR.

[0094] Before performing font recognition, first do some necessary preprocessing, such as the characters have been cut according to the strict principle that the vertical projection value is 0, the average Chinese character width / height, line height, and a...

Abstract

The invention discloses a kind of method and system to identify the font using the adherence, the characters are projected perpendicularly to get the character data of average Chinese characters and the row data of character; Chinese and English can be identified according to the ratio between the width of character and the average width and the first comparing threshold value; and then the characters are projected horizontally to get the pixel value at every projecting height; Chinese and English can be identified according to the relationship between the height with the pixel value at the height. The property of character can be identified exactly using the invention, and it improves the identifying efficiency, identifies the Chinese and the adhered English character, and improves the discrimination rate for the optical characters.

Description

technical field [0001] The present invention relates to a font recognition method and system, in particular to a method and system for recognizing the adhesion features of Chinese and English fonts. Background technique [0002] OCR (Optical Character Recognition) technology is closely related to the content to be recognized. From the perspective of printed OCR, there is a clear difference between most Western characters represented by English and Eastern characters represented by Chinese, Japanese, and Korean. of. The literature "Recognition of Mixed Chinese and English Articles" [Journal of Software, 1000-9825 / 2005 / 16(05)0786, authors Wang Kai and Wang Qingren] analyzed and pointed out that no OCR core technology can successfully recognize both Western and Eastern languages ​​at the same time. class text. Therefore, when recognizing mixed Chinese and English manuscripts, it is generally necessary to distinguish between Chinese and English first, and then hand them over t...
