This paper presents an audio-video surveillance system for the automatic surveillance in public transport vehicle. The system comprises six modules including in particular three novel ones: (i) Face Detection and Tracking, (ii) Audio Event Detection and (iii) Audio-Video Scenario Recognition. The Face Detection and Tracking module is responsible for(More)
Focusing on improving security in public transports (here: trains), this paper presents a research project implementing an audio-video surveillance system. Combining audio analysis, video tracking and dedicated integration of audio-video acquisition and storage equipments, the proposed system addresses the task of providing an operator with a(More)
This paper is focused on real time detection of satellite reception state. In constrained environment, such as urban areas, GNSS signals can be received directly, reflected or blocked by obstacles (building, vegetation, etc) and can lead to an error or a lack of positioning. This paper proposes to characterize the GNSS signals reception environment using(More)
