摘要
采用codebook算法进行前景目标检测,然后用粒子滤波跟踪算法进行运动跟踪,最后运用模拟退火算法对轨迹数据进行优化从而生成视频摘要。整个过程采用编码实现,生成的视频摘要将原来视频中不同时间段的活动压缩到同一时间段的一个短视频中,不仅缩短了时间,而且保证了所有信息的完整性。
This paper generated video synopsis by adopting codebook algorithm to improve the foreground object detection, and then using particle filter tracking algorithm for motion tracking, finally using simulated an- nealing original algorithm to optimize the trajectory data. Coding was adopted to realize the whole process. The activity of video in different periods is compressed into a short video of the same period. The generated short video synopsis not only shorten the time, but also ensured the integrity of all information.
