Abstract
A light field is a collection of multi-view images which represent
a 3D scene. Rendering from a light field provides a simple and efficient
way to generate arbitrary new views of the scene as the viewing position
and angle change, thus offering the experience of immersive viewing. The
enormous amount of data required in a light field poses a key challenge
in rendering. Tree-structured vector quantization (TSVQ) provides
moderate compression ratio of around 24:1, which alleviates but does not
solve the problem. Compression schemes based on video coding techniques
exploit the data redundancy very effectively, but do not provide
adequate random access for rendering. This paper describes a new
compression scheme that supports interactive rendering directly from
compressed light field data. The proposed algorithm provides a high
compression ratio of as much as 10 times that of TSVQ, while only
slowing down the rendering speed by a factor smaller than 2
