... Imagine that for every pixel in the color image, you take its luminance value (that's how bright it appears). ... In the end, you will have a histogram which counts how many times each luminance value appears in the image (that histogram can be used to analyze the distribution of the luminance values in the image). ... For the watermark effect, we want to use the same value that we used in the Stretch Contrast step, so that the lightest color will be in fact white (255), and nothing will get clamped...

Next: A Plea to Up: Some Problems of Practical Previous: Problems of Fourier . I would like to spend the rest of my time showing an example of the kind of dilemma one can get into when doing restorations.
