Tunable Q-Factor Wavelet Transform (TQWT) Version 1.3 This is a MATLAB implementation of the tunable Q-factor wavelet transform (TQWT) described in the paper. An implementation in C, which runs faster than the MATLAB code, is available by request. See the guide: TQWT_guide.pdf for more information. For questions/comments/etc contact selesi@poly.edu Reference: Wavelet Transform with Tunable Q-Factor http://taco.poly.edu/selesi/TQWT/ Ivan Selesnick selesi@poly.edu Polytechnic Institute of New York University Brooklyn, NY 11201, USA -------------------------------------------------- List of functions: tqwt_radix2.m Main function for the radix-2 TQWT. itqwt_radix2.m Inverse radix-2 TQWT. These functions use radix-2 FFTs only. tqwt.m TQWT (First form of TQWT described in the paper.) itqwt.m Inverse TQWT These functions are slower than tqwt_radix2. They are provided to complement the paper. The radix-2 versions are preferred for practical use. demo1.m Illustrates the use of functions. demo1_radix2.m test_PR_radix2.m Verify perfect reconstruction properties. test_PR.m sparsity_demo.m Reproduces Example 2 in the TQWT paper. resonance_demo.m Demonstration of resonance decomposition tqwt_sparsify_bp.m Finds sparse representation (basis pursuit) tqwt_sparsify.m Finds sparse approximation (basis pursuit denoising) tqwt_mca Resonance decomposition tqwt_mca_eq Resonance decomposition with equality constraint PlotFreqResps.m Plot frequency responses of the TQWT. PlotSubbands.m Plot subbands computed using TQWT. PlotEnergy Plot distribution of signal energy over subbands. PlotWavelets.m Plot wavelets associated with TQWT. ComputeWavelets.m Computes wavelets associated with TQWT. afb.m Analysis filter bank (called by tqwt and tqwt_radix2). sfb.m Synthesis filter bank (called by itqwt and itqwt_radix2). lps.m Low-pass scaling next.m Next power of two uDFT.m unitary DFT (normalized DFT) uDFTinv.m unitary inverse DFT (normalized inverse DFT) frequency_response_functions Folder containing functions called by Plot_FreqResps. -------------------------------------------------- Versions version 1.3 February 23, 2011 version 1.2 February 22, 2011 version 1.0 January 6, 2011
