Abstract: This paper presented an algorithm based on Stroke Fcaturc hriangle Model, adding calligraphy effect to points and lines sampled by computer, in order to beautify hand writing characters. Strokes arc formed by point set with calligraphy and character features. Algorithm based on Stroke Feature Triangle Model offers width to each part of strokes. I3-Spline Curves are used in smoothing of handwriting stroke outline. This method can offer precise calligraphy simulation in the fly of character handwriting, and has good portability between various equipments.

Key words: Character stroke,Calligraphy effects, Handwriting character beautification,Stroke feature triangle
