This chapter defines “image” and “image processing” for the purposes of this book. Given these definitions, it becomes evident that exact reproduction is never possible. It is shown that changes in images need not degrade quality, and that it is essential to use perceptually valid quality measures in evaluating processing methods. A generalized image processing system is devised to exhibit the wide range of phenomena associated with imaging apparatus and the correspondingly wide range of knowledge that can fruitfully be brought to bear on the subject. Finally, to make these considerations more explicit, a particular example of′a practical imaging system is discussed.
