摘要：
Integral imaging is a glasses-free 3D video technology that captures a light-field representation of a scene. This representation eliminates many of the limitations of current stereoscopic and autostereoscopic techniques. However, integral images have a large resolution and a structure based on micro-images which is challenging to encode. In this paper a compression scheme for integral images based on view extraction is proposed. Average BD-rate gains of 15.7% and up to 31.3% are reported over HEVC. Parameters of the proposed coding scheme can take a large range of values. Results are first provided with an exhaustive search of the best configuration. Then an RD criterion is proposed to avoid exhaustive search methods, saving runtime while preserving the gains. Finally, additional runtime savings are reported by exploring how the different parameters interact.
