摘　　要：由于立体视频的数据量巨大，不便存储和传输，因此必须进一步提高其压缩效率，降低传输的码率．文章分析了立体视频左右通道间恰可察觉失真的关系，基于立体掩蔽效应提出了非对称立体视频编码算法．实验结果表明：在解码重建图像主观质量基本不变的前提下，右视点视频编码的码率节约了11．45％～18．69％．与传统立体视频编码模型相比，该算法可以获得更好的立体视频压缩性能．It is inconvenient for stereoscopic video to be stored and transported due to huge amount of data, thus the compression efficiency must be further improved to reduce the transmission bit rate. The relationship of just noticeable distortion among stereoscopic video channels is analyzed, an asymmetric stereoscopic video coding scheme based on stereoscopic masking effect is proposed in this paper. The experimental results show that the proposed scheme can reduce the right viewpoint bit rate by 11.45%-18.69% with decoded reconstructed image maintaining almost the same subjective quality. The proposed algorithm achieves better stereoscope video compression performance compared with the traditional stereoscope video coding scheme.
