Abstract

In the paper highly efficient context image lossless coder of moderate complexity is presented. Three main plus few auxiliary contexts are described. Predictors are adaptive, enhanced RLS coefficient update formula is implemented. A stage of NLMS prediction is added. Prediction error bias is removed using a robust multi-source approach. An advanced adaptive context arithmetic coder is applied. Experimental results show that indeed, the new coder is both more effective and faster than other state-of-the-art algorithms.
