Simulation results with the COST 239 topology show that this hybrid protection scheme provides 10% better in network redundancy than a pure p-cycle scheme. Meanwhile, it retains the merits of the p-cycle for fast protection. 使用COST239网络拓扑进行的仿真实验表明:相同网络负载和波长资源条件下,p-cycle和p-path混合保护方案比p-cycle独立保护方案的网络冗余度可以优化10%,同时保留了p-cycle快速保护的优点。
Motion estimation is one of the most important part of motion compensation/ DCT based hybrid video coding standards which lead to high compression ratio by efficiently reducing temporal redundancy between adjacent frames of video sequence. 运动估计是基于运动补偿/DCT混合编码方法的重要组成部分,运动估计与补偿技术可以有效地去除视频序列相邻帧间存在的时间冗余,极大地提高了编码效率。
