Problems solved by technology

[0003] The existing character recognition technology is mainly based on feature extraction, which is sent to the feature classifier to output the final recognized character; while the fonts of English and Chinese characters are fixed, it is relatively easy to preprocess, but the structure of Tibetan has many changes , bytes also have many shapes, it is difficult to improve the recognition rate with the existing character recognition technology, and the accuracy rate of Tibetan character recognition is low

Abstract

The invention provides a Tibetan character recognition device and method, which relate to the field of character recognition. The Tibetan character recognition device and method receive a Tibetan character document image captured by a high-speed camera, according to the size of the Tibetan character document image, the line spacing of each line area, and the pre-set time of each suspected Tibetan character. The coordinates of the established coordinate system and the area of ​​the smallest rectangular frame of each suspected Tibetan character generate an adaptive threshold range associated with the characteristics of the Tibetan character in real time; if the attribute feature of the smallest rectangular frame outside each Tibetan character When it is not within the adaptive threshold generated in real time, the Tibetan characters within the minimum rectangular frame are segmented or merged, thus eliminating misrecognition of Tibetan characters for the special structure and byte shape of Tibetan In this case, the accuracy of Tibetan character recognition is improved.

Description

technical field [0001] The present invention relates to the field of character recognition, in particular to a Tibetan character recognition device and method. Background technique [0002] Tibetan traditional culture is a member of the splendid cultural cradle of China. Tibetan language has a long history and beautiful characters. There are countless ancient books and translations recorded in Tibetan language. In order to preserve these traditional excellent cultures for a long time, writing The informatization of Chinese characters is very important. In the current era of information technology, examples of informatization of characters are common. The recognition technology of English and Chinese characters is also very mature. [0003] The existing character recognition technology is mainly based on feature extraction, which is sent to the feature classifier to output the final recognized character; while the fonts of English and Chinese characters are fixed, it is relat...
