视频镜头边缘检测算法研究与比较

摘要

视频镜头边缘检测中的直方图、像素差异等算法只针对有限的测试数据进行了范围比较狭窄的测试,对于算法的适用领域和范围没有进行测试和说明.为了解决这一问题,设计实现了三种视频镜头检测算法,并构造了丰富的测试视频数据集,针对测试结果进行了实现算法的性能分析以及提出了改进建议.%Color histogram and pixel differences algorithms only test in a limited material. In order to research these algorithms ' used areas, this paper designed and implemented three algorithms and constructed a test video set. After test, it analyzed these algorithms' performance. And it concludes that a algorithm' s performance requires a trade-off between recall and precision that must be guided by the user' s demand.
