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 automatically extracting strokes of Chinese characters based on splitting and matching, which belongs to the technical field of pattern recognition and information processing. The skeleton diagram of stroke parts, find the intersection point in the skeleton diagram, and then calculate the PBOD curve of the two-dimensional neighborhood midpoint of the intersection point in the binary image, and extract the intersection area; 3. Extract features for stroke parts, the feature Matching with the features of the stroke components in the standard library; 4. Combining the stroke segments according to the matching results to obtain the strokes of Chinese characters. The present invention can achieve satisfactory extraction effects for Chinese characters with different fonts, effectively improve the unsatisfactory extraction accuracy and slow extraction speed of Chinese character strokes, and the accuracy of stroke extraction is also getting better as the standard font library becomes more and more comprehensive. come higher.

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...
