一种镜头淡入淡出检测算法

A Fade-in and Fade-out Detection Method

镜头检测与分割在视频检索中起着关键的作用。镜头切变识别已有许多成熟的方法。如何识别镜头渐变是视频分割中的难点。文章提出了一种基于直方图中颜色分量变化规律的镜头淡入淡出变换(fadein/out)识别方法。实验表明,该方法简单有效,且识别准确率较高。

Shot detection is one of the most important issues in the field of video retrieval.Some cut shot detection methods have been presented.Identifying gradual change in video sequences is the difficult point in video shot cut detection.This paper presents an algorithm for fade-in and fade-out scene change detection based on color-change in histogram.It is demonstrated that the approach is convenient and efficient ,especially with high reliability.
