AbstractThis paper studies the compression of a dynamic IBR representation called the simplified dynamic light fields (SDLF). It is obtained by constraining the viewpoints in a dynamic environment along a line instead of a 2D plane. The simplified dynamic light fields have a dimensionality of four, which considerably simplifies their capturing and data compression. A new coding algorithm for this simplified dynamic light fields using a modified MPEG2 algorithm is proposed. It employs both temporal and spatial predictions from the reference video streams to better explore the redundancy among the light field images. Experimental results, using a synthetic SDLF, show that the proposed compression scheme offers a 2 dB improvement in PSNR over a similar coding scheme using only temporal prediction.
