WFILT_HDEN - Higher DENsity dwt filters (tight frame, frame)

Usage

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

Description

[h,g,a]=wfilt_hden(K) with \(K \in {1,2,3,4}\) returns Higher DENsity dwt filters (tight frame, frame) from the reference. The filterbanks have 3 channels and unusual non-uniform subsamplig factors [2,2,1].

Examples:

wfiltinfo('hden3');

wfiltinfo('ana:hden4');
