滤波长度 meaning in Chinese

filter length

The construction of biorthonormal mras with filter length 4 and 5 is studied respectively
分别研究了所有滤波长度为4和5的双正交多尺度分析( mra )的构造。
In case of filter length 5 , both the existence of unique symmetric biorthonormal mra and the inexistence of antisymmetric ones are proved
并证明了，存在唯一的滤波长度为5的对称双正交小波，不存在滤波长度为5的反对称双正交小波。
This thesis focuses on the construction of biorthonormal multiresolution analyses ( mras ) with finite length filters , image compression and image watermarking based on wavelet transform
本论文主要研究滤波长度有限的双正交多尺度分析的构造和基于小波变换的图象压缩、图象隐形水印技术。
