Linear Image Processing

... format. 397 CHAPTER 24 Linear Image Processing Linear image processing is based on the same two techniques as conventional DSP: convolution and Fourier analysis. Convolution is the more important of these two, since images ... in image processing. For example, the Fourier transform of a 512×512 image requires several minutes on a personal computer. This is roughly 10,000 times sl...

... of the image at that point.When x, y, and the amplitude values of f are all finite, discrete quantities, we call the image a digital image. The field of digital image processing refers to processing digital ... antic- ipated. The area of image analysis (also called image understanding) is in be- tween image processing and computer vision. There are no clear-cut boundaries i...
