 基于栅格结构的正交小波滤波器组逼近方法 王洪剑; 彭思龙; WangHongjian; PenSilong, Source Publication 计算机辅助设计与图形学学报 2005 Volume 17(7) (EI)Issue:2005年07期Pages:1470-1475 Abstract In this paper，we present a kind of wavelet filter approximating method based on lattice structure．By virtues of the properties of the lattice structure，two processes，step—by—step lattice optimization and random lattice optimization，are adopted to construct wavelet filters．During the step-by— gtep lattice optimization，we give two selections：throw—out principle and remained principle，and the two selections are proved to be equivalent to each other．Thus the throw—out principle can ensure that our optimization algorithm is optimal in each step．And we also extend the kind of method to construct wavelet filter banks with different length．In this paper，the algorithm is successfully applied in the following problem：constructing two channel orthogonal wavelet filter banks close to linear phase and constructing signal．adapted wavelet filter banks with finite impulse responses(Principal Component Filter Banks)．Parts of results in the step—by-step optimization have been accepted by IEEE ICIP2003． Keyword 小波滤波器组 / 栅格结构 / 分步栅格优化和随机栅格优化 / 滤波器逼近 Document Type 期刊论文 Identifier http://ir.ia.ac.cn/handle/173211/12990 Collection 智能制造技术与系统研究中心_多维数据分析 Corresponding Author 王洪剑 Recommended CitationGB/T 7714 王洪剑,彭思龙,WangHongjian,等. 基于栅格结构的正交小波滤波器组逼近方法[J]. 计算机辅助设计与图形学学报,2005,17(7) (EI)(2005年07期):1470-1475.
