Region-based analysis

Abstract

This chapter is concerned with how we can characterise regions in an image, often by their texture. We shall first consider some of the grouping techniques that have been developed to form regions within an image. These essentially change the image resolution from high to very low. We shall then consider what is meant by texture and then how we can use Fourier transform techniques, statistics and region measures to describe it. We shall then look at how the measurements provided by these techniques, the description of the texture, can be collected together to recognise it.
