然而,目标跟踪过程中的遮挡问题会导致视频中目标信息的缺失,因此许多算法无法稳定地跟踪目标。 |
However, many state-of-the-art algorithms cannot track the interested object reliably due to occlusion during tracking process, which leads to deficiency of object information. |

使用谱聚类对点轨迹进行标记,以区分目标区域与背景区域,从而判断目标是否发生遮挡或漂移,决定是否启用重检测机制对目标进行检测。 |
These labeled points were used to differentiate the foreground and background objects and thus detect whether the target was occluded or drifts. If drifting and occlusion occur, re-detection was used to detect the re-entering of the target. |

鉴于多天线—非正交多址(MIMO-NOMA)系统中配对弱用户较差的中断性能,采用 Alamouti 码为弱用户编码,利用其分集作用来改善弱用户的中断性能,并推导出所提模型中强用户各态历经容量的闭合表达式以及弱用户各态历经容量、中断概率的边界表达式。 |
In view of the paired weak user’s poor outage performance in multiple-input multiple-output non-orthogonal multiple access (MIMO-NOMA) systems, Alamouti code was adopted to encode for the weak user in order to improve its outage performance by means of diversity, and the closed-form expression of the strong user’s ergodic capacity as well as the boundary-form expressions of the weak user’s ergodic capacity and outage probability was derived in the proposed model. |

最后,数值结果验证了所推表达式的准确性和所提算法的有效性,也证实了所提编码方案中弱用户的中断性能要远优于目前只采用垂直分层空时码(V-BLAST)编码方案中弱用户的中断性能。 |
Finally, the numerical results show the accuracy of the derived expressions, the efficacy of the proposed algorithm, and that the weak user's outage performance in the proposed coding scheme is far superior to that in the current coding scheme only adopting vertical Bell lab layered space-time (V-BLAST) code. |
