Basic processes of Chinese character based on cubic B-spline wavelet transform

In this paper, a novel approach based on cubic B-spline wavelet transform i s proposed to process Chinese character including character compression, ty pe zooming-in, and typeface composition. The basic idea is that a Chinese c haracter is described by its contours which are represented by cubic B-spli ne functions, and each contour is decomposed into the details or the contro l points (wavelet coefficients) at different resolution levels. For charact er compression, there are two methods, one directly treats the details of w avelet coefficients and the other considers the subcurves piecing together at the different resolution levels. In the type zooming-in, the wavelet rec onstruction is used to scale the Chinese character with arbitrary size and the wavelet filter is used to improve the quality of the enlarged type. For typeface composition, the new style typefaces of Chinese character are obt ained by editing and modifying the details at different resolution levels. The concrete algorithms are also given in this paper as well as the experim ental results.
