Publisher review:Toolbox Wavelets - Wavelet transform and coding functions, including other more exotic transforms toolbox_wavelets - wavelets related functions.Orthogonal wavelet transform:- perform_wavelet_transform - WAVELAB implementation of the wavelet transform.Wavelet transform using lifting implementation (symmetric boundary condition):- perform_lifting_transform / perform_lifting_transform_slow - 1D wavelet transform via lifting (general interface).- perform_lifting_transform_byname - string based interface.- perform_79_transform - biorthogonal 7/9 1D wavelet transform- perform_wavelet_transform_isotropic - multidimensional isotropic (i.e. classical) wavelet transform.- perform_wavelet_transform_hyperbolic - multidimensional hyperbolic (i.e. fully tensorial) wavelet transform.Pyramid transform:- perform_pyramid_transform - Laplacian-like pyramidal transform.- perform_pyramid_transform_do - Minh Do Pyramidal transform (much better).- perform_pyramid_transform_simoncelli - Steerable pyramid implementation of the Laplacian.- perform_pyramid_transform_ti - translation-invariance pyramid (difference of Gaussian filterings).Other transforms:- perform_haar_transform - a simple but very fast 1D haar transform.- perform_atrou_transform - compute the "a trou" wavelet transform, i.e. without subsampling (try to use either RWT or CWP2 when available).- perform_cpx_dualtree_transform - complex dual tree transform.- perform_steerable_transform - Steerable pyramid transform.Compression and coding function:- perform_jp2k_degradation - Perform JPEG2000 coding and decoding of wavelet coefficients.- perform_spiht_coding - Perform SPIHT coding (slow) of the wavelet coefficients.- perform_wavelet_arithmetic_coding - Perform simple arithmetic coding of the wavelet coefficients.- evaluate_nbr_bits_wavelets - compute the entropy of a wavelet transform.Helpers functions:- compute_quadrant_selection - compute the indices for selecting coefficients at a given scale and orientation.- reorder_coefs - switch from inplace (results of lifting transform) to classical ordering.- plot_wavelet - plot wavelet using Mallat's ordering.- convert_wavelets2list - extract each sub-image.Test scripts: see test_???.m files.Installation note : you need to add the content of toolbox/ in your Matlab path. Requirements: ยท MATLAB Release: R14
