This paper presents a region-based method for background subtraction. It relies on color histograms, texture information, and successive division of candidate rectangular image regions to model the background and detect motion. Our proposed algorithm uses this principle and combines it with Gaussian mixture background modeling to produce a new method which(More)
This paper proposed an efficient region-based background subtraction technique using static camera for motion detection in various monitoring applications. Color histograms, texture information, and successive division of candidate rectangular image regions are utilized to model the background and detect the motion. The proposed method combines this(More)
We propose an adaptive fuzzy particle filter (AFPF) method adapted to general object tracking with an IP PTZ camera. Particle filter samples are weighted using fuzzy membership functions and are applied to geometric and appearance features. In our particle filter, targets are modeled and tracked based on sampling around predicted positions obtained by a(More)
—In this paper, we propose a fuzzy feature-based method for online body tracking using an IP PTZ camera. Because the camera uses a built-in web server, camera control entails response time and network delays, and thus, the frame rate is irregular and generally low (3-7 fps). Our method has been designed specifically to perform in such conditions. It detects(More)
This paper describes current research combining computer vision, virtual reality and kinesiology for analyzing the cephalo-ocular behavior of drivers in realistic driving contexts. The different components of the system are described and results are provided for each one. The ultimate goal of the system is to achieve automatic analysis of drivers' behavior(More)
In this paper, we propose a method for online upper body tracking using an IP PTZ camera. This type of camera uses a built-in web server resulting in variable response times when sending control commands. Furthermore, communicating with a web server implies network delays. Thus, because the camera is inside a control loop, the effective frame rate that can(More)
A real-time lip tracking on very low contrast images acquired under near-infrared illumination is presented. We developed a modified particle filter tracker based on fuzzy logic that is appropriate for non-linear modeling and robust to the non-Gaussian noise. Fuzzy model is used to normalize the particle filter samples weights. Fuzzy membership functions(More)
