Chapter 7. Feature Generation II

7.1. Introduction

In the previous chapter we dealt with the task of feature generation via linear or nonlinear transformation techniques. This is just one of the possibilities available to the designer. There are a number of alternatives, however, that are very much application dependent. Although similarities among various applications do exist, there are also major differences. We will start by focusing on one major application area; that of image analysis. Clearly, we cannot review all techniques that have been suggested and used. Their number is really large. Instead, we will focus on basic directions, with a wide range of applications in mind, such as medical imaging, remote sensing, robot vision, and optical ...
