About the Cover (by Roger Dalal)
The elegant Nautilus, with its progressive chambers and near-perfect logarithmic spiral, demonstrates the beauty of mathematics and the power of digital image processing. Created exclusively for Practical Image and Video Processing Using MATLAB®, this composition features multiple layers and processing techniques. The primary image is doubly sharpened with an 8 pixel radius, and enhanced with posterizing and edge detection algorithms. The outer, secondary image is indexed to 20 colors, pixelized at two percent resolution of the center image, and partially hidden by a fading, offset radial mask.
