title: Finding the extrema of a region.
abstract: The computational difficulty of finding the extreme points (those two points furthest from each other) in a region of an image is examined. Various approaches are described, including computation of convex hulls, sophisticated search strategies, and a statistical method. Suitability of the various methods to particular applications is discussed.
