【摘要】 在视频镜头分割领域,近来出现了大量的算法,这些算法总体来说可以分为像素域和压缩域两种情况下的处理,同时也因选取的视频特征不同,可以适用于hardcut、fade、dissolve三种不同的镜头转换形式。该文主要对这些算法以及视频特征进行讨论,并进一步介绍了关键帧抽取方面的相关新的进展。更多还原

【Abstract】 A large number of shot se gmentation techniques have been developed in recent years.They all can be clas sified into two groups,pixel field and compressed field.The different approa ches select different video characters,consequently,each approach is applicab le to one of the three transitions,hard cut ,fade and dissolve.This paper mai nly discusses these Algorithms and video characters,furthermore,we introduce the advances on key frame extract.更多还原
