| 摘 要： | 对于镜头骤变检测，通过最小扩展树算法(MST)提取保留了视频帧空间信息的颜色聚合向量直方图、引入了动态自适应阈值和时间阻尼，使得骤变检测效率高；对于渐变检测，通过分析其数学产生模型，根据模型特性实现渐变镜头检测；最后，采用一个良好的融合策略同时完成骤变和渐变。

| Abstract: | The detection correctness of abrupt transition is improved by color coherence vector histogram using minimum spanning tree (MST) to keep video frames' spatial information, along with introducing adaptive threshold and time damping The detection of video gradual transition (fade and dissolve) is implemented based on the characteristics of production model Both the abrupt and gradual transitions are accomplished at the same time through a sound fusion strategy |

| Keywords: | minimum spanning tree (MST) color coherence vector (CCV) adaptive threshold production model fusion shot detection |
