我们提出了一种灵活的团队运动视频摘要框架,它能够整合有关显示内容的知识(例如兴趣水平,视图类型等),以及用户的个人(叙述)偏好。我们的框架建立在将原始视频序列划分为独立片段的基础上,并通过考虑多种方式来渲染每个片段来创建本地故事。我们讨论了如何根据生产原则对视频进行分段,并设计了效益函数来评估一个片段中的各种本地故事。通过选择本地故事的摘要被视为一个资源分配问题,并进行拉格朗日松弛,以找到最佳的。我们使用一个足球视频来验证我们的框架在我们的实验。
We propose a flexible summarization framework for team-sport videos, which is able to integrate both the knowledge about displayed content (e.g. level of interest, type of view, etc.), and the individual (narrative) preferences of the user. Our framework builds on the partition of the original video sequence into independent segments, and create local stories by considering multiple ways to render each segment. We discuss how to segment videos based on production principles, and design the benefit function to evaluate various local stories from a segment. Summarization by selection of local stories is regarded as a resource allocation problem, and Lagrangian relaxation is performed to find the optimum. We use a soccer video to validate our framework in our experiments.
