Abstract

DACLIC is a lossless/near lossless coding scheme that attempts to remove redundancy in a given image in spatial domain. Although the scheme is primarily used as a lossless image compression technique, it can be easily extended to near lossless compression application by introducing a small quantization loss. A Quadtree Rrice Coder (QRC) is proposed as an entropy coder of DACLIC. An arithmetic coder is also given as an option. Further, a postprocessing technique is introduced to remove the banding artifacts in the DACLIC system.
