Lepton image compression, saving 22% losslessly from images at 15MB/s. Lepton achieves a 22% savings reduction for existing JPEG images, by predicting coefficients in JPEG blocks and feeding those predictions as context into an arithmetic coder. Lepton preserves the original file bit-for-bit perfectly. It compresses JPEG files at a rate of 5 megabytes per second and decodes them back to the original bits at 15 megabytes per second, securely, deterministically, and in under 24 megabytes of memory. ...

Multi-threaded HDF5 filter implementing the LPC-Rice codec. This lossless codec is intended to compress correlated signal data, such as image data, stored in HDF5 chunks. The codec/filter is optimized for both compression and decompression speed, but compression ratios are still comparable to JPEG-LS and CCSDS-123 codecs.

Rududu will be a wavelet video codec.

PyramidWorkshop is an image-compression System based upon the scientific work of John Robinson (inventor of BTPC) about image-compression with adaptive linear predictors and is in average more efficient than PNG/JPEG2000.

Infinity is a fractal compressor (based on high mathematical theories) done by a university assigment. It will be based on neural networks (an innovative approach) and coded in C++
