摘要
视频序列的镜头分割亦称镜头变化检测是视频检索中的关键技术之一.对五种常用的视频分割算法作了综述,包括像素法、直方图法、X2直方图法、X2直方图分块法、边缘轮廓变化率法,并详细介绍了各种算法中的帧差异值的计算以及介绍了了他们的优缺点,并且通过实验分析对各种算法进行了比较,五种算法的优缺点实验中得到了很好的体现.
Partitioning a video sequence into shots or detecting shot change is one of the key techniques in video indexing. This article summarizes some commonly used methods for partitioning video into shots which are pixel level-based methods, histogram methods, X2 histogram methods, X2 block histogram methods, edge silhouttee rat of changing mathods, and detailedly introduces various algorithms of frames difference value calculation, and introduces the advantages and disadvantages of them, and the results of these algorithms are compared through the experiments, the advantages and disadvantages of Five algorithm at the experiments are very well reflected.
