Gaussian Wavelet Denoising Software (GaussianWaveDen)

Various wavelet shrinkage estimators for denoising Gaussian measurements are implemented in MATLAB™. These estimators arise from a wide range of classical and empirical Bayes methods treating individual or blocks of empirical wavelet coefficients either globally or in a level-dependent fashion.

The description of the various methods and the results of an extensive simulation study have appeared in:

Antoniadis, A., Bigot, J. & Sapatinas, T. (2001). Wavelet estimators in nonparametric regression: a comparative simulation study. Journal of Statistical Software, 6, Issue 6, 1-83.

Please click on article, MATLAB™ 5.2, and html-help to download the above article, the MATLAB™ routines used in the simulation study, and the corresponding help-html files.

Poisson Wavelet Denoising Software (PoissonWaveDen)

Various wavelet shrinkage estimators for denoising Poisson measurements are implemented in MATLAB™. These estimators arise from a wide range of classical and empirical Bayes methods treating individual empirical wavelet coefficients either globally or in a level-dependent fashion.
