EPSILON is a powerful OpenSource wavelet image compressor.
Wavelet-driven compressors are know to be much more effective
than traditional DCT-based ones (like JPEG). At the moment,
the program supports 30+ different wavelet filters, runs
in parallel in multi-threaded and MPI environments, can
process HUGE images and much more!
