WFILT_QSHIFTB Improved Orthogonality and Symmetry properties Usage: [h,g,a] = wfilt_qshiftb(N); [h,g,a]=WFILT_QSHIFTB(N) with N in {1,2,3,4,5,6,7} returns Kingsbury's Q-shift wavelet filters for tree B. Examples: --------- : figure(1); wfiltinfo('qshiftb3'); References: N. G. Kingsbury. A dual-tree complex wavelet transform with improved orthogonality and symmetry properties.
