Summary
In addition to the image enhancement applications that we used as illustration in this and the preceding chapter , the concepts and techniques developed in thes two chapters provide the basis for other areas of image processing addressed in subsequent discussions in the book . Intensity transformations are used frequently for intensity scaling and spatial filtering is used extensively for image restoration in the next chapter,for color processing in Chapter 6, for image segmentation in Chapter 10, and for extracting descriptors from an image in Chapter 11. The Fourier techniques developed in this chapter are used extensively in the next chapter for image restoration, in Chapter 8 for image compression, and in Chapter 11 for image description
