Color Image Segmentation Using Energy Minimization on a Quadtree Representation
Abstract. In this article we present the results of an unsupervised segmentation algorithm based on a multiresolution method. The algorithm uses color and edge information in an it...

A context adaptation model for the compression of images with a reduced number of colors
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 ...
