Predictor blending technique for lossless and near-lossless image coding
Grzegorz Ulacha, Ryszard Stasiński · 2008
In the paper a lossless image coding method intended for real-time hardware intra-frame video coding system is described. Data modeling stage of the method is based on predictor blending idea, the following entropy coding stage is realized as an advanced adaptive context arithmetic coder. The stages can be separated by a quantizer, in which case the coder is becoming a near-lossless one. Experiments show that indeed, the new algorithm is not only time efficient, but has also excellent data compression performance.
