Riassunto

This book addresses one of the central problems in computer-aided image analysis; how the shape of structures in an image should be represented to best facilitate quantitative analysis. To accomplish this task requires an understanding of what shape is and how it should be extracted from grey-scale images. In Professor Gauch's book a new shape description for grey-scale images called the intensity axis of symmetry (IAS) and an associated curvature-based description called vertex curves are presented.
