摘　　要：在对一类广义多分辨模型研究基础上，以样条函数空间为例，全面剖析了基于Ｂ样条函数的多分辨塔式结构与算法，并详细给出了各滤波器参数。对一维信号与二维图象的仿真研究表明该算法简洁、快速，具有推广应用价值。In this paper, the research results of a general multiresolution model are put into the splines function space. The Structure of multiresolution pyramid based on B-splines and its algorithm is analyzed, and the parameters of each filter are also given. The simuultation researches of one--dimension signal and two--dimension image demonstrate that this algorithm is fast and it can be easily generalized and put into practice
