简介

This book/CD-ROM set provides an integrated treatment of stochastic halftoning and digital printing. This second edition incorporates updated models, algorithms, and methods used to construct and improve the quality of green-noise, blue-noise, and multi-tone images. New topics covered include stochastic moir茅 in color printing, and a blue-noise model for multi-toning applications where the target printing device is capable of printing multiple shades of the same color ink. There is a new chapter on lenticular printing, a means for printing color holographic images. The art program features numerous b&w and a few color images. The CD-ROM contains MATLAB software files and illustrated examples employing algorithms, statistics, and other key concepts from the book.
