Video Processing and Computational Video

The goal of image-based rendering is to evoke a visceral sense

of presence in a scene using only photographs or videos. A huge variety of

different approaches have been developed during the last decade. Exam-

ining the underlying models we find three different main categories: view

interpolation based on geometry proxies, pure image interpolation tech-

niques and complete scene flow reconstruction. In this paper we present

three approaches for free-viewpoint video, one for each of these categories

and discuss their individual benefits and drawbacks. We hope that study-

ing the different approaches will help others in making important design

decisions when planning a free-viewpoint video system.
