EN In the paper currently the most efficient from the data compaction point of view image lossless coding method is presented. Being computationally complex the algorithm is still more time efficient than its main competitors. The method is based on weighted LS (WLS) technique idea with many improvements introduced, e.g. its main stage is followed by a two-step NLMS predictor. Prediction error is coded by a completely new highly efficient binary context arithmetic coder. Its performance is compared with that of other coders for a set of widely used benchmark images.
