摘　　要：为了解决复杂曲线的小波分解问题,根据B样条小波的综合滤波器的特点,给出了GaussB样条半正交小波的快速分解算法.Cardinal B-spline wavelets have been widely used in multi-resolution modeling for curves and surfaces. The size of coefficient matrix for the orthogonal decomposition is usually too large to solve and to allocate enough memory in a computer if the B-spline curve has a huge number of control vertices. Gauss algorithms for the quick decomposition of such a B-spline curve were introduced using B-spline semi-orthogonal wavelets in the paper.
