摘要
En 中文
This paper presents a high efficiency video codec-based spatial mixed-resolution stereo video codec. The proposed codec applies a frame interleaving algorithm to reorder the stereo video frames into a single stream of monoscopic video. The challenge for mixed-resolution video coding is to enable the codec to encode frames with different frame resolutions. This issue is addressed by superimposing a low-resolution replica of the decoded I-frame on its respective decoded picture, where remaining space of the frame is set to zero. This significantly reduces the computation cost for finding the best match. The proposed codec's reference frames structure is designed to efficiently exploit both temporal and inter-view correlations. The performance of the proposed codec is assessed using five standard multiview video data sets and benchmarked against that of the anchor and the state-of-the-art techniques. Results show that the proposed codec yields significantly higher coding performance compared with the anchor and state-of-the-art techniques.
