| 中文摘要: |
| 立体视频流在易发生错误的信道中传输时会发生丢包现象，导致无法正确解码，影响观看效果。本文提出基于H.264平台的立体视频隐藏算法，依据最小代价函数值模式自适应选择两种不同算法，一种利用视点间运动矢量和强度差的相似性来隐藏；另一种采用边界匹配法选择两个候选块权值叠加隐藏。仿真结果表明本文算法比其他算法显著改善了隐藏效果，具有很强的鲁棒性。 |
| 英文摘要: |
| Stereoscopic video stream is prone to loss pocket in the process of transmissions, which lead to error decode and influence on displaying effect. A stereoscopic video error concealment algorithm based on H.264 is proposed, which can adaptively select two methods according to minimum cost function value model. A kind of method based on the inter-view similarity of motion vectors and intensity differences for the concealment and another method based on boundary matching to combines two candidate blocks for the concealment are proposed. Simulation results demonstrate that the proposed algorithm provides significantly better performance than other algorithms, which have more robustness. |
