Audio-Visual Fused Online Context Analysis Toward Smart Meeting Room

چکیده
Context-aware systems incorporate multimodal information to analyze contextual information in users’ environment and provide various proactive services according to dynamic context. In this paper, a novel online context analysis framework is proposed to support context-aware computing in smart meeting room. A novel dynamic context model is presented to model human group interactions. Robust audio and visual modules are integrated for the effective processing of multimodal signals from various sensors, based on which a multi-level dynamic context reasoning mechanism is adopted for the online understanding of group interactions in meeting scenarios. Experimental results show the effectiveness of our framework.

An Adaptive Vision System Toward Implicit Human Computer Interaction
In implicit human computer interaction, computers are required to understand users’ actions and intentions so as to provide proactive services. Visual processing has to detect and understand human actions and then transform them as the implicit input. In this paper an adaptive vision system is presented to solve visual processing tasks in dynamic meeting context. Visual modules and dynamic cont...
متن کاملMultimodal Analysis for Universal Smart Room Applications
Abstract This paper presents a multimodal system incorporating smart room technologies (SRT) for conference room applications. Although, the audio-visual analysis requires only rather basic equipment, the system works reliably and supports various applications such as recognizing persons using different modalities, localizating visible speakers, controlling the camera view and summarizing the A...

متن کاملReverberation-Robust Online Multi-Speaker Tracking by Using a Microphone Array and CASA Processing
Online tracking of speakers is an important task for applications in smart environments such as camera control, meeting annotation and speech separation. Challenges for an audio-only system are small-room reverberation, noise, the unknown number of speakers, and gaps occurring in natural speech. Combining models from neurobiology and cognitive psychology with many-channel signal processing and ...
متن کاملSMaRT: the Smart Meeting Room Task at ISL
As computational and communications systems become increasingly smaller, faster, more powerful, and more integrated, the goal of interactive, integrated meeting support rooms is slowly becoming reality. It is already possible, for instance, to rapidly locate task-related information during a meeting, filter it, and share it with remote users. Unfortunately, the technologies that provide such ca...
