WFILT_SYMDDEN Symmetric Double-Density DWT filters (tight frame) Usage: [h,g,a] = wfilt_symdden(K); [h,g,a]=WFILT_SYMDDEN(K) with K in {1,2} returns oversampled symmetric double-density DWT filters. The redundancy of the basic filterbank is equal to 1.5. Examples: --------- : wfiltinfo('symdden1'); : wfiltinfo('symdden2'); References: I. Selesnick and A. Abdelnour.
