Background Modeling Using Phase Space for Day and Night Video Surveillance Systems
نویسندگان
چکیده
This paper presents a novel background modeling approach for day and night video surveillance. A great number of background models have been proposed to represent the background scene for video surveillance. In this paper, we propose a novel background modeling approach by using the phase space trajectory to represent the change of intensity over time for each pixel. If the intensity of a pixel which originally belongs to the background deviates from the original trajectory in phase space, then it is considered a foreground object pixel. In this manner, we are able to separate the foreground object from the background scene easily. The experimental results show the feasibility of the proposed background model.

Nowadays automated early warning systems are essential in human life. One of these systems is fire detection which plays an important role in surveillance and security systems because the fire can spread quickly and cause great damage to an area. Traditional fire detection methods usually are based on smoke and temperature detectors (sensors). These methods cannot work properly in large space a...

Video surveillance is used in monitoring the road traffic. However because the surveillance system is limited by many objective factors. Surveillance video may not be seen clearly. Especially under the weak light conditions, the picture quality of the night video is very poor. In this paper, we propose an enhancement method of nighttime images for surveillance camera. We apply the moving target...
