Abstract

This paper is an attempt to bring together a number of current ideas in multiresolution image processing into a single framework. The unification is achieved by introducing a two-level image model, comprising a quadtree containing parameters which control the evolution of the image as a sequence of successive refinements through scale-space. Examples of the method's application to image coding and analysis are used to illustrate the principles and show its usefulness.
