一种改进的视频镜头切变检测算法

An Improved Algorithm for Detecting Video Abrupt Change

介绍了现有典型切变检测方法,提出了一种改进的镜头切变检测算法,利用像素法和直方图法相结合,有效避免了像素法导致的误检问题和直方图法导致的漏检问题,取得了较好的实验效果。同时引入一种闪光检测方法,避免了因闪光导致的误检问题。

In this paper, some typical abrupt change detection algorithms are introduced, and then an improved algorithm for detecting shot abrupt change is proposed, which combines pixel-based method and histogram-based method, so the false detection problem of pixel-based method and the missed detection problem of histogram-based method can be avoided effectively. Our experiments show that this method provides good result. At the same time a method for flashlight detection is proposed to avoid the false detection problem because of certain flashlight.
