Embodiment Construction

[0054] Below in conjunction with accompanying drawing, further describe the present invention through embodiment, but do not limit the scope of the present invention in any way.

[0055] After the glyph cutting algorithm is completed, the original character image of the Chinese character, the images of all the parts obtained by cutting the Chinese character, the category to which the parts belong, and the strokes contained in the parts can be obtained. The present invention provides a method for judging the correctness of the results of the glyph cutting algorithm. The method sequentially includes a judging process based on glyph reconstruction, a judging process based on component classification, a judging process based on glyph attributes, and a judging process based on glyph skeletons. , figure 2 It is a block flow diagram of the glyph cutting result correctness discrimination method provided by the invention, and the concrete process is as follows:

Abstract

The invention discloses a method for determining the correctness of a cutting result of a Chinese character pattern, and belongs to the field of automatic extraction of strokes and parts of Chinese characters. The method sequentially comprises a discrimination process based on character pattern reconstruction, a discrimination process based on part classification, a discrimination process based on character pattern attributes, and a discrimination process based on a character pattern skeleton. When a discrimination result of a to-be-discriminated pattern cutting result in any discrimination process is a wrong cutting result, the to-be-discriminated pattern cutting result is determined as a character pattern cutting error. The method can recognize 97% of the wrong cutting results or more. Therefore, the method can effectively determine the cutting errors.

Description

technical field [0001] The invention belongs to the field of automatic extraction of strokes and parts of Chinese characters, and relates to a method for discriminating the cutting results of Chinese characters, in particular to a method obtained by using four discrimination algorithms of font reconstruction, font attributes, component classification and font skeleton for a font cutting algorithm. A method for judging the correctness of the cutting results. Background technique [0002] The glyph cutting technology of Chinese characters includes automatic extraction of Chinese character strokes and automatic extraction of Chinese character components. Chinese character glyph cutting technology was initially used as a preprocessing step in the optical character recognition process, using the results of glyph cutting to assist the recognition of Chinese characters. With the continuous development of glyph calculation technology, Chinese character glyph cutting technology has ...
