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_jbig_coding.m - Perform JBig binary image coding (not related to wavelet). - perform_spiht_coding - Perform SPIHT coding (slow) of the wavelet coefficients. - perform_wavelet_arithmetic_coding - Perform simple arithmetic coding of the wavelet coefficients. - perform_shannon_estimation_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. Copyright (c) 2006 Gabriel Peyré
