Mixed-resolution HEVC based multiview video codec

Studies have shown that mixed resolution based video codecs, also known as asymmetric spatial inter/intra view video codecs are successful in efficiently coding videos for low bitrate transmission. In this paper a HEVC based spatial resolution scaling type of mixed resolution coding model for frame interleaved multiview videos is presented. The proposed codec is designed such that the information in intermediate frames of the center and neighboring views are down-sampled, while the frames still retaining the original size. The codec's reference frames structure is designed to efficiently encode frame interleaved multiview videos using a HEVC based mixed resolution codec. The multiview test video sequences were coded using the proposed codec and the standard MV-HEVC. Results show that the proposed codec gives significantly higher coding performance over the MV-HEVC codec at low bitrates.
