Abstract :
This paper proposes a low complexity multi-view video encoder which includes mode decision and early termination based on B-frame characteristics. According to the statistics of coding mode distribution in different B-frame types, we classify all the coding modes into several classes and propose an early terminated mode decision algorithm that can largely reduce the computing complexity. On the other hand, MVD-based adaptive search range scheme is also included in the proposed encoding strategy. In our experimental results, the encoding time is saved up to 91%-93% but the quality loss is controlled within 0.1 dB PSNR drop.
