Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0032] The invention splits Chinese characters into stroke parts and performs refinement and extraction of intersecting regions, then extracts the features of the stroke parts and matches them with the features of the stroke parts in the standard library, and combines the stroke segments according to the matching results to realize the stroke extraction of Chinese characters . Through a large number of experiments, it has been verified that the stroke extraction method can achieve satisfactory extraction results for Chinese characters of different fonts, effectively improve the unsatisfactory extraction accuracy of Chinese character strokes, and the shortcomings of slow extraction speed. It has good scalability in terms of rate and efficiency.

[0033] Using strokes and components as feature vectors to describe Chinese characters has better st...

Abstract

The invention discloses a method for extracting automatically character strokes based on splitting and matching, and belongs to the technical field of pattern recognition and information processing. The method comprises the steps as follows: Step one, splitting a character into multiple stroke components according to a character structure; Step two, extracting a skeleton diagram of the stroke components, finding junctions in the skeleton diagram, then calculating PBOD curves of points which are in the neighborhoods of the junctions in a binary image, and extracting junction areas; Step three, extracting features for the stroke components, wherein, the features are matched with features of the stroke components in a standard library; and Step four, combining stroke segments according to the matched result and obtaining strokes of the character. According to the invention, the satisfactory extraction effect can be achieved for the characters with different fonts, the deficiencies that the character stroke extraction accuracy is not ideal and the character stroke extraction speed is slow can be improved effectively, and the stroke extraction accuracy is also high increasingly after the standard character library is complete increasingly.

Description

technical field [0001] The invention relates to a method for automatically extracting strokes of Chinese characters based on splitting and matching, which is used for Chinese character recognition and belongs to the technical field of pattern recognition and information processing. Background technique [0002] Due to the special importance of Chinese characters in our country, Chinese character recognition has broad application prospects, such as document retrieval, office automation, sorting of postal letters, automatic reading of test papers, etc. role. At the same time, Chinese character recognition is also an important aspect of scientific theoretical research, and its research will also promote the research and development of various disciplines. As the application of Chinese character recognition becomes more and more popular, the requirements for the speed and accuracy of Chinese character recognition in the application system are also getting higher and higher. Onc...
