Low-Complexity and Sampling-Aided Multi-view Video Coding at Low Bitrate

In this paper, a sampling-aided multi-view video coding (MVC) scheme for low-bitrate applications is explored. With the proposed method, original views are first downsampled and reorganized into a single view. Next, the reorganized view is sent to the conventional video encoder, compressed and reconstructed. At the decoder, each decoded frame will be split into separate views and upsampled back to the original resolution. Experimental results on several high definition (HD) multi-view sequences show that, compared with the simulcast coding scheme, the proposed method presents superior rate-distortion performance at low-bitrate cases with significant complexity reduction for both encoding and decoding.
