摘要:

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。

Abstract:

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.

Key words: video abstraction, local-space model, key-frame, mutual information
