WFILT_ALGMBAND - An ALGebraic construction of orthonormal M-BAND wavelets with perfect reconstruction

Usage

[h,g,a] = wfilt_algmband(K);

Description

[h,g,a]=wfilt_algmband(K) with \(K \in {1,2}\) returns wavelet filters from the reference paper. The filters are 3-band (\(K==1\)) and 4-band (\(K==2\)) with critical subsampling.

Examples:

wfiltinfo('algmband1');

wfiltinfo('algmband2');
