Currently, a raw light field image can be captured by a light field camera and decomposed into multi-views with different perceptual quality. A novel light field compression approach for a light field image is proposed based on this observation, where the raw light field image is decomposed into multi-views as pseudo-sequencing frames and reordered according to their perceptual quality. The resulting pseudo-temporal sequence is then compressed by high-efficiency video coding (HEVC) encoder. Experimental results show that the proposed method can achieve a better coding performance (up to 28% Bjontegaard delta bit rate reduction (BDBR) savings) compared with state-of-the-art reordering techniques using HEVC.
