be helpful to students. Continuous wavelet transform, along with some con-
tinuous wavelet functions, have been examined. Multiresolution analysis for
wavelets can be used to design spline wavelets using splines of various degrees.
One of the areas involving B-spline wavelet transform and multiresolution is
the Chinese character processing, which can be found in [158]. The work is
based on three stages, namely pre-processing, wavelet transform, and objec-
tive processing. Initially, a Chinese character is represented by its contours.
Each contour with its coordinates is interpolated by a cubic B-spline function.
The coecient sequences, called the control points of the B-spline interpola-
tion curves, are then linked with the coordinate points of the contour curves.
Multiresolution analysis is then used to describe the interpolated curves. The
topic [158] describes several algorithms using both the global and local ap-
proaches for objective processing of curves.
