About the cover:
The first image on the left is the peppers_gamma original color image.
The second image is the edge map of the luma component of the first image produced by a derivative of
Gaussian edge detector.
The third image is the cat original color image.
The fourth image is the spatial gain image of the luma component of the cat image produced by a Wallis
statistical differencing operator.
The fifth image is the result of Wallis processing on the luma component and amplitude stretching of the
chrominance components of the cat image.
The lower right image is a sharpened version of the original image obtained by subtracting an amplitude
weighted version of the blurred image from a weighted version of the original image. The processing
technique is called unsharp masking.
