A new simple context lossless image coding algorithm based on adaptive context arithmetic coder

Abstract

In the paper an effective context based lossless coding technique is presented. Three principal and one auxiliary contexts are defined. Cumulated predictor error combining 8 bias estimators is calculated. An adaptive context arithmetic coder is introduced. It is shown experimentally that the new technique is time-effective while it outperforms the well known methods having reasonable time complexity, and is inferior only to extremely computationally complex ones.
