This paper proposes an efficient lossless coding scheme for still images. The scheme employs a block-adaptive prediction technique to remove spatial redundancy in a given image. The resulting prediction errors are encoded using context-adaptive arithmetic coding. Several coding parameters, which must be sent to a decoder as side information, are iteratively(More)
SUMMARY A highly efficient Iossless encoding method for static images is proposed. In this method, multiple linear predic-tors are created for each image and adaptive prediction that responds to the local structure of images such as edges and textures is achieved by switching between these predictors at the block level. Furthermore, the probability density(More)
