Introduction

Abstract

The subject of this book is image segmentation by variational methods. The focus is on formulations which use closed curves to define the segmentation regions and on a level set implementation of the corresponding active curve evolution algorithms. In broad terms, image segmentation consists of dividing an image domain into disjoint regions according to a characterization of the image within or in-between the regions. Therefore, segmenting an image is to divide its domain into relevant components.
