基于局部-空间模型的视频摘要研究与设计

摘要

This paper represents the background and the significance of video abstraction technology, as well as the three types of research method for video abbreviation. A research method is proposed for video abstraction based on local-space model. In the model, the key frame is got by the analysis of the intra-frame and inter-frame video sequence information, and these key frames are extracted to construct the video segment by double-interpolation. With the DES in the DirectShow software, the video segments are edited and fused into a final dynamic video abstraction.Experimental results show that the video abstraction is generated automatically without any article intervention, which contains the main information of the video but little redundant information.%介绍视频摘要技术以及缩略视频的3类研究方法,提出一种基于局部-空间模型的视频摘要研究方法.通过对视频序列的帧内与帧间信息的分析得到关键帧,对提取出的关键帧进行双线性插值形成视频段,运用DirectShow开发软件的DES对视频段编辑融合成最终的动态视频摘要.实验结果表明,在不需要人工干预的情况下,自动生成的视频摘要不仅包含视频的主要信息,而且冗余信息少.
