A Note on Zeng's Technique for Color Reindexing of Palette-Based Images
Armando J. Pinho, António J. R. Neves · IEEE Signal Processing Letters · 2004
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.
