The Progressive Graphics File (PGF) is an efficient image file format, that is based on a fast, discrete wavelet transform with progressive coding features. PGF can be used for lossless and lossy compression. It's most suitable for natural images. PGF can be used as a very efficient and fast replacement of JPEG 2000.

libdwt is a cross-platform discrete wavelet transform library implemented in C language. The library implements fast wavelet transform algorithm using lifting scheme. Cohen-Daubechies-Feauveau wavelets with 4 vanishing moments were used.

Rududu will be a wavelet video codec.

EPSILON is a powerful Open Source wavelet image compressor. The project is aimed on parallel and robust image processing.

Scilab Wavelet Toolbox, is designed to emulate Matlab Wavelet Toolbox. Combined with Scilab Image processing toolbox on sourceforge, one could do image wavelet processing the way as the Matlab user does.

A library written in C for lossy image compression. Library libopen/format OPEN supports two methods of compression - discrete cosine transform (used in JPEG) and discrete wavelet transform (used in JPEG2000).

Image recognition program for granulometry analysis. Based on wavelet transform and levelset method.

The watermark package provides an application for wavelet-based invisible robust image watermarking.
