摘要
提出一种基于亮度帧差的自适应镜头边界检测算法。通过计算视频图像帧之间的亮度差来自适应检测视频镜头的转换,并且加入一些简单而有效的判断,和传统的方法相比较,可有效提高镜头检测的检出率和准确率,实验证明可快速准确进行实时的镜头分割。
We put forward a method based on the AIFD(absolute-intensity-frame-difference) to detect the shot boundary. Based on the AIFD and some simple and effective methods, we can detect more accurately than the traditional ways. The experiment shows that we can detect the shot boundary quickly and accurately in real time.
