Calligraphy image processing with stroke extraction and representation

Calligraphy is the art of writing and each writer has his own features, where calligraphy strokes carry the most important features. In order to identify the stroke and the writer, this paper proposes an approach of stroke extraction and presentation. Firstly, skeleton segments of the character are extracted according to the writing rules. Secondly, neighbouring common segment strokes are connected to build a complete stroke, followed by special short stroke backtrack. Thirdly, individual outline strokes are isolated by using curves to build the closed contour for the stroke. Finally, generate and save outline strokes for future stroke feature extraction. Our approach can extract strokes from parts of regular script and official script.
