It is research code which was designed to perform wavelet compression at high speed in software, and therefore contains some of the worst elements of both genres. (Consider yourself forewarned!) No future releases are planned for this code. This code will compile as is on Sun Solaris 2.x machines. It will not compile/work correctly under DOS, due to byte ordering issues. Since all storage/computations are integer both lossless and lossy compression are available. However the lossless compression does not give terribly good compression rates. The wavelet transform : Daubechies 5-3 scaled up by root 2. Quantizer: constant, nearly uniform. Highpass encoding: Huffman with escape codes for large numbers Lowpass encoding: fixed width. (A hook is available for adding JPEG-LS if you are willing to code it yourself.) For further technical details of the wavelet transform, quantizer, and entropy encoding, see the documentation directory.
