  • Representation and Description

    An external representation is chosen when the primary focus is on shape characteristics. An internal representation is selected when the primary focus is on regional properties, such as color and texture. Sometimes it may be necessary to use both types of representation. In either case, the features selected as descriptors should be as insensitive as possible to variations in size, translation, and rotation. For the most part, the descriptors discussed in this chapter satisfy one or more of these properties.
