Abstract
Recently, Chen et al. proposed a method for compressing color-quantized images that is based on a binary tree representation of colors and on context-based arithmetic coding with variable size templates. In this paper, we address the problem of context adaptation and we propose a model that provides improvements in the lossless compression capabilities of Chen´s method.
