Title: 異機種端末に適応した個人化ビデオの自動生成
Other Titles: Autonomous Production of Personalized Videos for Heterogeneous Terminal Devices
Authors: CHEN, Fan

Abstract: 複数撮影視点からの情報統合により、高精度な追跡や映像解析ができるほか、映像の表現方式にも高い自由度を与えた。我々はスポーツテレビ及び映像監視システムを応用事例とし、語義上の内容選択、時間軸上の要約及び空間軸上の画面構成の三つ階層から、異機種端末に適応した個人化ビデオの自動生成を検討した。追跡された対象を群相互作用により個体群に分ける。個体群の間に閲覧対象を遷移し、配信内容を選択する。更に、ユーザーの好みと端末の性能に対する最適な再生速度及び画面構成を自動的に決定する 。研究期間中で特許一点、論文誌論文五篇、解説論文一篇、国際会議論文十一篇(全査読付き)を発表し、展示会に二回出展した。 : 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.
