Abstract

We study a method of representing space efficiently quadtrees, octrees and related pixel trees. Its efficiency of encoding two-dimensional black-and-white and multicolour images is compared to that of established methods such as chain encoding. For both two- and three-dimensional images we show that beside quad- and octrees it is relevant to consider also pixel trees based on a binary division of space. A paged storage scheme is proposed for accessing encoded pixel trees by spatial location.
