README ********************************** 1. Introduction This package is a free collection of Matlab routines for computing wave atom transforms in one, two and three dimensions. The implementation is described in detail in the following two papers: (a) L. Demanet, L. Ying, Wave atoms and sparsity of oscillatory patterns, to appear in Appl. Comput. Harmon. Anal. 2007. (b) L. Demanet, L. Ying, Curvelets and wave atoms for mirror-extended images, technical report. 2007. Both of them can be downloaded from www.waveatom.org. ********************************** 2. List of files Most of the transform functions have two versions: standard and symmetric. In the standard version, the coefficients are organized in a cell array as described in the papers. In the symmetric version, the coefficients are stored in an array. The symmetric version is particularly useful for applications like thresholding. 1D wave atom transform fwa1.m - forward transform iwa1.m - inverse transform fwa1sym.m - forward transform, symmetric version iwa1sym.m - inverse transform, symmetric version 2D wave atom transform fwa2.m - forward transform iwa2.m - inverse transform fwa2sym.m - forward transform, symmetric version iwa2sym.m - inverse transform, symmetric version 3D wave atom transform fwa3.m - forward transform iwa3.m - inverse transform fwa3sym.m - forward transform, symmetric version iwa3sym.m - inverse transform, symmetric version 2D mirror-extended wave atom transform mefwa2.m - forward transform meiwa2.m - inverse transform mefwa2sym.m - forward transform, symmetric version meiwa2sym.m - inverse transform, symmetric version 2d mirror-extended curvelet transform mefcv2.m - forward transform meicv2.m - inverse transform test functions test_wa1.m - display several members of 1D wave atom orthobasis test_wa2.m - display several members of 2D wave atom orthobasis test_wa3.m - display one member of 3D wave atom orthobasis test_wa2_reconstruction.m - partial image reconstruction using wave atoms test_wa2_denoising.m - image denoising using 2D wave atom frame with hard thresholding and cycle spinning test_mewa2.m - display several 2D mirror-extended wave atoms test_mecv2.m - display several 2D mirror-extended curvelets test_mewa2_reconstruction.m - partial image reconstruction using mirror-extended wave atoms test_mecv2_reconstruction.m - partial image reconstruction using mirror-extended curvelets internal functions freq_pat.m g.m kf_lf.m kf_rt.m cvwindow.m mescatter.m mecombine.m dct2.m idct2.m data files data_fingerprint.jpg - fingerprint image from Chris Brislawn data_seismic.jpg - seismic data from Eric Verschuur and Felix Herrman ********************************** 3.
