A Multimodal Distributed Intelligent Environment for a Safer Home

This paper presents an ambient intelligence system aimed at increasing the security of elderly people in their living environment. The proposed system processes both video and audio signals to detect dangerous events and trigger automatic warnings. The system is implemented through a software middleware for multimedia streaming and processing in which the information is processed in several, distributed software nodes. This paper focuses on the fall detection video processing node and on the sound classification and localization audio processing node. The system has been tested both in a laboratory and in a real-world scenario, demonstrating high performance levels.
