Title: ビデオストリームのエンティティベースの時間的セグメント化
IPC: H04N21/845
Filed: 2016-04-13
Abstract: ビデオのビデオフレーム内の識別されたエンティティの分析に基づいて、ビデオを時間的にセグメント化するための解決策が提供される。ビデオは、複数のビデオフレームへ復号され、複数のビデオフレームは、アノテーションの付与のために選択される。アノテーションプロセスは、サンプルビデオフレーム内に存在するエンティティを識別し、各識別されたエンティティは、タイムスタンプと、そのエンティティが正確に識別される尤度を示す信頼度スコアとを有する。各識別されたエンティティについて、タイムスタンプと、対応する信頼度スコアとから構成される時系列が、生成され、平滑化されて、アノテーションノイズが低減される。ビデオの長さにわたるエンティティを含む1つまたは複数のセグメントは、エンティティの時系列においてセグメントの境界を検出することによって取得される。ビデオ内の各識別されたエンティティについての個々の時間的セグメント化から、ビデオについての全体的な時間的セグメント化が生成され、ここで、全体的な時間的セグメント化は、ビデオの意味論を反映する。
