Meeting Recording System via Multimodal Sensing
نویسندگان
چکیده
In this paper, we propose a recording system for a round-table meeting using microphone array as well as omnidirectional video camera. These equipments are located at the center of the table, and record all the activity during a meeting. They are also used for estimating the directions of speakers, and such data is exploited for reproducing the frontal image of the speaker from omnidirectional image. Experimental results using the prototype system are also shown.

Joint Audio-Visual Tracking Using Particle Filters
It is often advantageous to track objects in a scene using multimodal information when such information is available. We use audio as a complementary modality to video data, which, in comparison to vision, can provide faster localization over a wider field of view. We present a particle-filter based tracking framework for performing multimodal sensor fusion for tracking people in a videoconfere...
متن کاملUsing Static Documents as Structured and Thematic Interfaces to Multimedia Meeting Archives
Static documents play a central role in multimodal applications such as meeting recording and browsing. They provide a variety of structures, in particular thematic, for segmenting meetings, structures that are often hard to extract from audio and video. In this article, we present four steps for creating a strong link between static documents and multimedia meeting archives. First, a document-...
متن کاملMultimodal summarization of meeting recordings
Recorded meetings are useful only if people can find, access, and browse them easily. Key-frames and video skims are useful representations that can enable quick previewing of the content without actually watching a meeting recording from beginning to end. This paper proposes a new method for creating meeting video skims based on audio and visual activity analysis together with text analysis. A...

متن کاملA research agenda for assessing the utility of document annotations in multimedia databases of meeting recordings
The recording, multimodal analysis and archiving of meetings introduce new challenges for research in multimedia information management. Meetings involve multiple media that can be aligned together. This requires a global annotation framework. In particular, meetings often deal with documents, either projected or discussed, which can be aligned with the audio and video streams. This article pre...
