In this paper, we report work on a family of variable-length codes with less redundancy than the de facto flat code used in most of the variable size dynamic dictionary based comp...

Abstract. It is well-known that the lossless compression of color-indexed images can be improved if a suitable reordering of the palette is performed before encoding the images. In...
