1 Introduction

Digital image signals are typically represented as two-dimensional (2D) arrays of discrete signal samples. If we rearrange the signal samples into a one-dimensional (1D) vector, then every image becomes a single point in a high-dimensional image space, whose dimension equals the number of samples in the image signal. It has been pointed out that the cluster ...
