WFILTDT_DDEN Double-Density Dual-Tree DWT filters Usage: [h,g,a] = wfiltdt_dden(N); [h,g,a]=WFILTDT_DDEN(N) with N in {1,2} returns filters suitable for dual-tree double density complex wavelet transform. Examples: --------- : wfiltdtinfo('dden1'); : wfiltdtinfo('dden2'); References: I. Selesnick. The double-density dual-tree DWT. Signal Processing, IEEE Transactions on, 52(5):1304--1314, May 2004.
