[...]... (ISO) standard library of image processing operators and associated utilities.” Again, for a fourth time, a new edition of Digital Image Processing is offered to the image processing community Why? One reason is because advances in the theoretical aspects of image processing technology continue at a rapid rate For example, in the year 2005, the IEEE Transactions on Image Processing published 2191 pages... maximum intensity of an image, for example, film saturation and cathode ray tube (CRT) phosphor heating Hence it is assumed that 0 < C ( x, y, t, λ ) ≤ A (1. 1-1 ) Digital Image Processing: PIKS Scientific Inside, Fourth Edition, by William K Pratt Copyright © 2007 by John Wiley & Sons, Inc 3 4 CONTINUOUS IMAGE MATHEMATICAL CHARACTERIZATION where A is the maximum image intensity A physical image is necessarily...
