MATLAB implementation of W-matrix multiresolution analyses
IL (United States) Argonne National Lab., Man Kam Kwong · 1997
We present a MATLAB toolbox on multiresolution analysis based on the W-transform introduced by Kwong and Tang. The toolbox contains basic commands to perform forward and inverse transforms on finite 1D and 2D signals of arbitrary length, to perform multiresolution analysis of given signals to a specified number of levels, to visualize the wavelet decomposition, and to do compression. Examples of numerical experiments are also discussed.
