libPGF is an implementation of the Progressive Graphics File (PGF)
The Progressive Graphics File (PGF) is an efficient image file format, that is based on a fast, discrete wavelettransform 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.
a cross-platform discrete wavelettransform library implemented in C
libdwt is a cross-platform discrete wavelettransform library implemented in C language. The library implements fast wavelettransform algorithm using lifting scheme. Cohen-Daubechies-Feauveau wavelets with 4 vanishing moments were used.
Implements Lazy WaveletTransform with Lifting in several variants: 1-D, 2-D, 3-D, integer precision, etc. Sample video compressor, integrated with FFmpeg. OpenCL version is created.
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 wavelettransform (used in JPEG2000).

MongoDB Atlas gives you the freedom to build and run modern applications anywhere—across AWS, Azure, and Google Cloud. With global availability in over 115 regions, Atlas lets you deploy close to your users, meet compliance needs, and scale with confidence across any geography.
Clean implementation (in ANSI-C) of the Wavelets Transform. It works fairy good as a sparser, which can be combined with a compression algorithm (by using programs like bzip and gzip) to achieve high compression ratios (as good as mp3's).
