RLGR Entropy Coder

Established: October 31, 2000

We have developed an efficient entropy coder for integer value data. We refer to this compression algorithm as a Run-Length Golomb-Rice (RLGR) coder. The RLGR coder is very simple to implement, and uses backward adaptation of just a few parameters,…
