摘要 为有效避免闪光和字幕对镜头检测造成的影响,提出了一种基于颜色空间的镜头边界检测方法。通过分析帧间亮度差在镜头边界处的特点,加入有效的判断方法,实现镜头的突变和渐变检测。 To effectively avoid the impacts caused by flashes and subtitles to shot detection,the paper proposes a shot boundary detection method based on colour space.By analysing inter-frames brightness difference of the lens border,we can fulfil the detection of lens mutation or gradient with effective method.
