Recent years have seen dramatic progress in shape recognition algorithms applied to ever-growing image databases. The book describes a complete method that starts from a query image and an image database and yields a list of the images in the database containing shapes present in the query image.

In image processing, "motions by curvature" provide an efficient way to smooth curves representing the boundaries of objects. In such a motion, each point of the curve moves, at any instant, with a normal velocity equal to a function of the curvature at this point.
