We previously proposed a method for designing predictors which can minimize a coding rate of prediction errors in lossless coding of still images. In this paper, we extend the method to lossless coding for volume data. Simulation results indicate that coding rates of the proposed lossless coding scheme are 0.02〜0.07 bit/voxel lower than those of the scheme using predictors designed on the MSE criterion.
