The Science of Digital Media

by Jennifer Burg

Three companion textbooks on digital media were published by Prentice-Hall in August 2008:

A Primer of Digital Media by Yue-Ling Wong (introductory level)
The Art of Digital Media by Yue-Ling Wong (for art students)
The Science of Digital Media by Jennifer Burg (for computer science and other science/math students)

Instructors can get a guest account and see a demo of The Science of Digital Media at the Prentice-Hall website.
