fast lossless compression, implementing Golomb-Rice coding
Project homepage: https://gitlab.dkrz.de/k202009/libaec
Description
Libaec provides fast lossless compression of 1 up to 32 bit wide
signed or unsigned integers (samples). The library achieves best
results for low entropy data as often encountered in space imaging
instrument data or numerical model output from weather or climate
simulations. While floating point representations are not directly
supported, they can also be efficiently coded by grouping exponents
and mantissa.
Libaec implements extended Golomb-Rice coding as defined in the
CCSDS recommended standard 121.0-B-3. The library covers the
adaptive entropy coder and the preprocessor discussed in sections
1 to 5.2.6 of the standard.
