Abstract

An H.264-based fast 3-D video compression algorithm is presented by reducing coding complexity of P slices in a depth map sequence using a fast-mode decision scheme. On the basis of the relationship of coding modes of collocated macroblocks on texture and depth frames, an early SKIP-mode decision scheme and a selective prediction-mode decision scheme have been developed to rapidly encode depth map sequences. Experimental results show that the algorithm can save the entire encoding time by 79% on average compared to conventional a depth map sequence coding algorithm, while introducing only negligible loss in peak signal-to-noise ratio value.
