Abstract

Full-parallax light field displays utilize a large volume of data and demand efficient real-time compression algorithms to be viable. Many compression techniques have been proposed. However, such solutions are impractical in bandwidth, processing or power requirements for a real-time implementation. Our method exploits the spatio angular redundancy in a full parallax light field to compress the light field image, while reducing the total computational load with minimal perceptual degradation. Objective analysis shows that depending on content, bandwidth reduction from two to four orders of magnitude is possible. Subjective analysis shows that the compression technique produces images with acceptable quality, and the system can successfully reproduce the 3D light field, providing natural binocular and full motion parallax.
