COMPUTER VISION FOR VISUAL EFFECTS

Modern blockbuster movies seamlessly introduce impossible

characters and action into real-world settings using digital visual

effects. These effects are made possible by research from the ﬁeld of

computer vision, the study of how to automatically understand images.

Computer Vision for Visual Effects will educate students, engineers, and

researchers about the fundamental computer vision principles and

state-of-the-art algorithms used to create cutting-edge visual effects for

movies and television.

The author describes classical computer vision algorithms used on

a regular basis in Hollywood (such as blue screen matting, structure

from motion, optical ﬂow, and feature tracking) and exciting recent

developments that form the basis for future effects (such as natural

image matting, multi-image compositing, image retargeting, and view

synthesis). He also discusses the technologies behind motion capture

and three-dimensional data acquisition. More than 200 original images

demonstrating principles, algorithms, and results, along with in-depth

interviews with Hollywood visual effects artists, tie the mathematical

concepts to real-world ﬁlmmaking.

Richard J. Radke is an Associate Professor in the Department of Elec-

trical, Computer, and Systems Engineering at Rensselaer Polytechnic

Institute. His current research interests include computer vision prob-

lems related to modeling 3D environments with visual and range

imagery, calibration and tracking problems in large camera networks,

and machine learning problems for radiotherapy applications. Radke

is afﬁliated with the NSF Engineering Research Center for Subsurface

Sensing and Imaging Systems; the DHS Center of Excellence on Explo-

sives Detection, Mitigation and Response (ALERT); and Rensselaer’s

Experimental Media and Performing Arts Center. He received an NSF

CAREER award in March 2003 and was a member of the 2007 DARPA

Computer Science Study Group. Dr. Radke is a senior member of the

IEEE and an associate editor of IEEE Transactions on Image Processing .
