PARAMETRIZATION FOR BALANCED MULTIFILTER BANKS
Baobin Li, Lizhong Peng · International Journal of Wavelets Multiresolution and Information Processing · 2008
The parametrization for two kinds of multifilter banks generating balanced multiwavelets is presented in this paper. In case (I), both lowpass and highpass filters are flipping filters. Filters in case (II) have different lengths, and both lowpass and highpass filters are symmetric (antisymmetric). Based on these parametric expressions, some balanced multiwavelets and analysis-ready multiwavelets (armlets) are constructed. Moreover, the application of these multiwavelets constructed in image processing is also studied.
