... format.397CHAPTER24Linear Image Processing Linear image processing is based on the same two techniques as conventional DSP: convolutionand Fourier analysis. Convolution is the more important of these two, since images ... in image processing. For example, the Fouriertransform of a 512×512 image requires several minutes on a personalcomputer. This is roughly 10,000 times slower than needed for real time image processing, ... Viewed image FIGURE 24-8Model of image formation. A viewed image, (c), results from the multiplication of an illuminationpattern, (b), by a reflectance pattern, (a). The goal of the image processing...
