| 摘 要： | 视频关键帧提取是视频信号处理中的一个重要内容。由于一个镜头中视觉内容的变化具有连续性,本文采用了距离累加的算法;同时,为了提高检测相邻帧间的相似度,本文将颜色特征与运动变化信息相结合,提出一种关键帧提取方法。实验证明,与过去的关键帧提取方法相比,本文算法提取的关键帧能较完整地表现序列图像的运动过程,更有利于对视频内容的理解。

| Abstract: | Video key frame extraction is an important part of video signal processing.In this paper,we propose a new key frame extraction method.As the visual change in a shot is continuous,the method of cumulative distance is adopted;color features and motion information are integrated to improve the detection precision of adjoining frames’ similarities and differences.Experiment results show that the new method proposed in this paper is superior to traditional methods based on color histogram and particle equivalent in that the key frames extracted with the new method give a better picture of the movement of sequential images. |
