Abstract

We previously proposed a method for designing predictors with could minimize a coding rate of prediction errors for lossless coding of still images. In this paper, we extend the method to near-lossless coding. Simulation results indicate that coding rates of the proposed scheme are 0.06〜0.29 bits/pel lower than those of JPEG-LS near-lossless coding.
