2004 IEEE Signal Processing Letters  
Palette reindexing is a well-known and very effective approach for improving the compression of color-indexed images. In this letter, we address the reindexing technique proposed by Zeng et al. and we show how its performance can be improved through a theoretically motivated choice of parameters. Experimental results show the practical appropriateness of the proposed modification. Index Terms-Color-indexed image compression, lossless image compression, palette reindexing.
