摘要
从离散的观点出发 ,提出了一种基于样条的最小均方离散滤波器 ,并给出了其在塔式多分辨分解和小波分解中的递推公式 ,最后通过和经典的 L P和最小均方 L P分解的比较实验 ,表明给出的滤波器非常适用于图象编码。
This paper provides a kind of least square discrete filter based on spline with discrete squence,and a successsive recursive structure is also deduced in multiresolution pyramid decomposition and wavelet decomposition, finally, a comparison is made between LP,least square LP and the method described here.The result shows that the filter presented in this paper is applicable in image coding.
