Abstract :
JPEG-LS is a lossless and near-lossless compression algorithm for continuous-tone images. As many variable length source coders, it is highly vulnerable to channel errors. In this paper, some modifications to the JPEG-LS are suggested. The modified algorithm has good robustness to channel errors, while maintaining a compression ratio that is close to that of the original JPEG-LS
