Abstract

A coder for light fields is presented. Due to the large amount of data needed to represent a complete light field, a hierarchical decomposition is employed. The full light field is built up by recursively predicting intermediate images from a small subset of lightfield images. Intermediate images are predicted by disparity-compensating multiple surrounding images. The predicted images are refined using DCT coding. Rate-distortion measurements for two standard light fields verify the efficiency of the proposed scheme. Compression ratios of 1000:1 are achieved at acceptable quality of the rendered views. 1. INTRODUCTION Common computer graphics rendering schemes are based on descriptions of object geometry, texture properties and illumination conditions. Photorealistic rendering results require very detailed geometry models and the computationally demanding simulation of global illumination effects. Acquisition of geometry information from natural objects is difficult and can even prov...
