摘　　要：提出了自适应的多视点视频编码(Multi-view video coding,MVC)视点间预测结构算法。首先根据视点间相似度分析确定I-视点的位置,然后利用相机的几何关系预测I-视点和P-视点之间插入B-视点的数目,灵活调整视点间预测结构,提高编码效率。实验表明,所提出的算法与视点间独立编码相比,PSNR平均提高1. 28 d B。In this paper, an adaptive inter-view prediction structure algorithm for multi-view video coding (MVC) was proposed.The position of the I-viewpoint was determined according to the similarity analysis between the viewpoints .Then, the geometric relationship of the camera was used to predict the number of B-viewpoints inserted between the I-viewpoint and the P-viewpoint.The inter-viewpoint prediction structure was flexibly adjusted to improve the coding efficiency.Experiments showed that the proposed algorithm has an average PSNR increase of 1.28 dB compared with the independent coding between views.
