Highly effective predictor blending method for lossless image coding
Grzegorz Ulacha, Ryszard Stasiński · 2010
A fast and effective predictor blending method is described in the paper. The special set of 17 blended predictors is defined, including GAP+, and (novel) texture context mapping one. An advanced error bias removal method is applied to some subpredictors. A sophisticated adaptive context arithmetic coder forms the final stage of the algorithm. Experimental results show that indeed, for considered execution times (few seconds for Lennagrey image) the presented technique is better than other state-of-the-art methods.
