CHAPTER 24 Statistical Pattern Recognition

24.1 Introduction

The earlier chapters of this book have concentrated on interpreting images on the basis that when suitable cues have been found, the positions of various objects and their identities will emerge in a natural and straightforward way. When the objects that appear in an image have simple shapes, just one stage of processing may be required—as in the case of circular washers on a conveyor. For more complex objects, location requires at least two stages—as when graph matching methods are used. For situations where the full complexity of three dimensions occurs, more subtle procedures are usually required, as has already been seen in Chapter 16. The very ambiguity involved in interpreting ...
