技術摘要 / Our Technology: |
一種數位視訊檔案檢索之圖像合成處理方法及系統,其可應用於處理一數位視訊檔案,用以對該數位視訊檔案提供一檢索圖像合成處理功能;且其特點在於首先從監視場景之視訊檔案中建立出背景影像;接著於有目標物體出現於監視場景中時,追蹤各個目標物體的動向及辨識其形態特徵而求得一組動向及特徵屬性資料,並從各個目標物體的視訊影像序列中選擇出一代表性影像;最後將各個目標物體的代表性影像及其動向狀態所對應之一組動向標籤和其特徵圖像疊加至於該背景影像之上,即可合成所需之檢索圖像。
A method and system is proposed for generating index pictures for video streams, where the index pictures can be used in a video database for visual browsing by users to quickly find and retrieve video clips or files from the video database. The proposed method and system operates in such a manner as to first create a set of content items of particular interest or concern (particularly moving objects), and then combine each content item together with an associated activity record dataset in a predefined manner into a single image to serve as an index picture. In practice, each moving object and its associated activity record dataset can be displayed by means of 2D (two-dimensional) or 3D (three-dimensional) graphic icons or imagery.
