Handwriting Chinese character input method and Chinese character identification method based on stroke segment mesh

Abstract

The invention discloses a Chinese character framework information representation, a handwritten Chinese character input method, a Chinese character recognition method without training, which are based on the stroke segment gridding. The Chinese character framework information representation is to set a stroke segment gridding formed by N multiplied by N small rectangles, which has the wired or wireless state and the stroke segment aggregate in the wired state represents a character framework. The input method is to portrayal the stroke segments in the stroke segment gridding, which are obtained and marked with the wired state by the computer. The recognition method has the following steps of: inputting the stroke segment gridding character framework of the Chinese character to be recognized, matching the basic strokes and the complex strokes thereof with the stroke segment gridding character framework of every Chinese character in the Chinese character information base, obtaining an optimal strokes matching method, working out the distance, and outputting the first M smallest-distance matched gridding character framework as the candidate recognition result for the importer to choose. The inventive method can input and recognize a plurality of Chinese characters as the original appearance, including the erroneous characters, the variant characters, etc, to improve the teaching and research of Chinese characters.

Description

technical field The invention relates to a method for expressing Chinese character fonts based on stroke grids, a method for inputting handwritten Chinese characters and a method for recognizing Chinese characters. No need to learn and train in advance, regardless of whether the character is written correctly, Chinese characters can be input into the computer according to the original appearance of the writing and be recognized. computer recognition. The invention belongs to the technical fields of pattern recognition, artificial intelligence and Chinese character information processing. Background technique With the rapid development of China's economy and the continuous deepening of foreign economic and cultural exchanges, more and more foreigners are interested in Chinese and learning Chinese. In the process of Chinese teaching, foreign students urgently need a computer Chinese character input method that can be used without training, without distinguishing and analyzi...

Problems solved by technology

The reason for the problem is that the only information that contains glyphs in the computer is the glyph, but the glyph not only contains glyph skeleton information, but also includes calligraphy information, the creator's understanding of the glyph and expression habits, etc., which is very complicated. So that it is difficult to automatically judge whether the two fonts are the same character

From the above analysis, it can be seen that the reason why arbitrary Chinese characters cannot be input into the computer is that the input software is closed, and the computer Chinese character processing software does not store the skeleton information of Chinese characters separately.
