| 摘 要： | 镜头分割是视频检索的结构化基础,为此提出一种高效的视频镜头分割方法.首先,在压缩域中提取视频流中I帧携带的特征信息,并生成帧间特征分布曲线;然后,利用离散曲线演化(DCE)算法对预处理过的曲线进行分析与演进;最后,分割出视频镜头并提取关键帧.试验结果表明:该方法充分考虑了视频编码的时序特点,具有较好的分割效果,鲁棒性强.

| Abstract: | Shot segmentation is structural base for video retrieval.An efficient video shot segmentation method is proposed.Firstly , the features are extracted from I frame of video stream in the compressed domain , and the curve of feature information is drawn.Then , the discrete curve evolution ( DCE ) algorithm is used to evolved the curve.Finally , video shots are segmented and key frames are extracted by the key points of the curve.The experimental results show that the method is efficient and robust , because it takes fully into account the timing features of video encoding. |
