Abstract

A rate-distortion optimized scheme for interactive light field streaming is proposed. The light field data set is transformed into blocks of wavelet coefficients; each block is coded as a scalable bitstream and stored at the sender. To render a frame, the receiver issues a request for relevant data. Based on the request, the estimated state of the data already at the receiver, the network characteristics, and the desired transmission rate, the sender customizes the outgoing packets in order to minimize the distortion experienced at receiver. Experimental results show that the proposed rate-distortion optimized scheme improves the rendering quality by 0.5~2.1 dB in PSNR over a heuristic scheme at the same rate. Alternatively, it reduces the required bit-rate by 10%~25% over the heuristic scheme at the same rendering quality.
