A stroke separation method based on Chinese character contours

Abstract

The invention provides a stroke separation method based on a Chinese character contour, which comprises the following steps: extracting the contour of a Chinese character, determining an inner contourand an outer contour, and obtaining a combined contour set; extracting contour candidate feature points of stroke separation; aiming at any candidate feature point; calculating the distance between any two feature points in the feature point set, the input vector and the output vector of each feature point, and initializing a feature point pair list; calculating a cosine included angle corresponding to the two feature points if the distance between the first feature point and the second feature point is not greater than a threshold value between any two different feature points; if a preset condition is met, adding the first feature point and the second feature point into a feature point pair set; and performing stroke separation based on the contour set, the feature point set and the feature point pair set. By applying the embodiment of the invention, through feature point position detection and angle detection, the accuracy of effective feature point screening is improved, and the accuracy of independent stroke extraction is improved.

Description

technical field [0001] The invention relates to the technical field of Chinese character contour extraction, in particular to a stroke separation method based on the Chinese character contour. Background technique [0002] Chinese characters have a long history of nearly 5,000 years of evolution and are widely used. With the development of computers and information technology, people's needs for various styles of fonts are becoming more and more urgent and diverse. [0003] Although there are many methods for separating independent natural strokes of Chinese characters, the relative separation accuracy and efficiency are relatively low. Due to the diversity of Chinese calligraphy and printing fonts, generating a beautiful computer vector font requires a lot of labor and low efficiency. Among the current vector fonts such as TTF, only a few fonts have independent stroke outline information for teaching use, and only have the stroke information of commonly used simplified cha...

Problems solved by technology

This is because there will be errors in the search and pairing of contour feature points, the extraction of skeleton points, and the optimization algorithm in these methods, which leads to the need to improve the accuracy of independent stroke extraction of Chinese characters
