PVCAIS: a personal videoconference archive indexing system

Wilh the rapid deployment of videoconference, the fast-accumulated personal videoconference archives need to be effectively indexed. This paper proposes a well-designed indexing system - PVCAIS that integrates many multimedia-indexing techniques to manage personal videoconference archives. Firstly, the contents of video, audio, text and whiteboard communications are stored after removing the redundancies. Next, more information, e.g., participants, title, keywords and slides, is extracted by face detection and recognition, speech recognition, OCR, automatic title generation, keyword selection, etc. Then, an XML index file containing the summary of the videoconference is also generated. The whole indexing process is automatic except that the face of a new contact needs to be interactively identified for only once. Finally, we demonstrate a graphical user interface which allows the user to search and browse the indexed videoconference archives conveniently.
