Line-space Representation and Compression for Image-based Rendering

In image-based rendering applications, images of a scene are captured along a specific camera trajectory and are then used to render new views of the scene. In this paper, we first study several possible camera trajectories and analyze their pros and cons. Then we introduce the line space which is a representation of light rays and use it to analyze a number of implementation issues in image-based rendering. We propose a novel sprite-based compression scheme in this application. The performance of the image compression under this scheme is examined.
