Autonomous Production of Personalized Videos for Heterogeneous Terminal Devices

多视角信息融合不仅能够实现精确的视频分析（例如，对象跟踪和场景理解），而且还为内容呈现提供了高度灵活性。以体育视频广播和智能视频监控为例，从语义故事组织、时间摘要和空间摄影规划三个不同层面，讨论了个性化视频的制作，以便在各种终端设备上更好地呈现内容。在将跟踪对象划分为相互交互的组之后，我们通过在交互组之间转移浏览目标来组织故事。然后，故事将通过自适应快进和虚拟缩放来呈现，以更好地满足用户偏好和设备限制所定义的条件。我们已申请1项专利，发表了5篇评论期刊论文，1篇教程论文，11篇评论国际会议论文，并参加了两次展览。

Multi-view information fusion not only enables accurate video analysis (e.g. object tracking and scene understanding), but also provides high flexibility to content presentation. Given sport video broadcasting and intelligent video surveillance as two use cases, we discussed the production of personalized videos for better presentation on various terminal devices, by considering content remixing from three different levels, i.e. semantic story organization, temporal summarization and spatial camerawork planning. After dividing tracked objects into mutually interactive groups, we organize the story by shifting the browsing target between interactive groups. The story is then rendered with adaptive fast-forwarding and virtual zooming to better satisfy the conditions defined by users preferences and device limitations. We have applied for 1 patent, published 5 reviewed journal papers, 1 tutorial paper, and 11 reviewed international conference papers, and attended two exhibitions.
