A Kai style contour beautification method for Chinese handwriting characters

In this paper, we propose a novel contour-based method to beautify online handwritten Chinese character to the Kai style calligraphy. According to the feature and structure of Kai style calligraphy, Bezier curve is used to sketch the user-input stroke segment contour and the corner contour. We get the whole contour path of beautified character by connecting stroke segments´ contour and corners´ contour end-to-end. Anti-aliasing technology is used to make the edge of the contour fine and smooth. Finally, the path-fill algorithm is adopted to fill the inner of the contour. Our system is proved to be effective and efficient. Meanwhile, users can choose any color for the contour and the inner, which is more convenient for users´ design.
