【摘要】 将一段无序的视频有序化、结构化,然后对视频进行自动编目和索引是现代媒体内容管理的一个新课题。本系统用双值门限检测镜头的渐变,利用镜头的时间和空间特征,计算出镜头间的距离。然后,利用上述两种物理特征结合的方法进行镜头聚类,可从视频流中根据视频所反映内容的变化生成有结构的视频目录。最后,应用一个结构化视频内容的编目原型系统,证明了该技术的有效性。更多还原

【Abstract】 The method, making the video without order into the one with order and structure, is a new task in modern media content management. Dual-value threshold was used to detect the transformation of shot. Spatial and temporal characteristics of shot were used to compute distance between shots. Then structured video was gained by using the above two methods to cluster shots. At last, a video cataloging prototype system of structured video content is used to prove the effectiveness of the technology.更多还原
