| 摘 要： | 在多分辨率曲线和曲面造型中,B样条小波已经得到广泛应用.为了进行小波分解,通常要解一个线性方程组或者求矩阵的逆.如果曲线比较复杂,控制点较多,则矩阵的阶数就会很大,所需的内存将难以容忍,小波分解的速度也会受到很大影响.根据B样条小波的综合滤波器的特点,给出了带宽B样条半正交小波的快速分解算法.

| Abstract: | 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.Band matrix algorithms for the quick decomposition of such a B-spline curve were introduced using B-spline semi-orthogonal wavelets in the paper. |
