Color image quantization by pairwise clustering
Luiz Carlos Pacheco Rodrigues Velho, José Gabriel R. C. Gomes, Marcos Vinicius Rayol Sobreiro · 2002
This paper presents a new quantization method for color images. It uses a local error optimization strategy to generate near optimal quantization levels. The algorithm is simple to implement and produces results that are superior than those of other popular image quantization algorithms.
