In this paper we present an effective system for detecting vehicles in front of a camera-assisted vehicle (preceding vehicles traveling in the same direction and oncoming vehicles traveling in the opposite direction) during night time driving conditions in order to automatically change vehicle head lights between low beams and high beams avoiding glares for(More)
This paper describes a comprehensive combination of feature extraction methods for vision-based pedestrian detection in the framework of intelligent transportation systems. The basic components of pedestrians are first located in the image and then combined with a SVM-based classifier. This poses the problem of pedestrian detection in real, cluttered road(More)
The goal of this paper is to develop a method for estimating the 2D trajectory of a road vehicle using visual odometry. To do so, the ego-motion of the vehicle relative to the road is computed using a stereo-vision system mounted next to the rear view mirror. Feature points are computed using Harris detector. After that, features are matched between pairs(More)
This paper describes a stereo-vision-based candidate selection method for pedestrian detection from a moving vehicle. Non-dense 3D maps are computed by using epipolar geometry and a robust correlation process. Non-flat road assumption is used for correcting pitch angle variations. Thus, non obstacle points can be easily removed since they lay on the road.(More)
This paper describes a method for estimating the vehicle global position in a network of roads by means of visual odometry. To do so, the ego-motion of the vehicle relative to the road is computed using a stereo-vision system mounted next to the rear view mirror. Feature points are matched between pairs of frames and linked into 3D trajectories. The(More)
Cybercars and dual mode vehicles are presently the most innovative testbeds for vehicular automation applications. The definition of standards and control architectures of the different automatic vehicle onboard systems is a necessary task to build a final prototype to be produced. Several classical architecture definitions have been made in the field of(More)
In this paper, an end-to-end Quality of Service (QoS) framework for streaming services in 3G mobile networks is considered. A solution based on a Public Land Mobile Network (PLMN) hosted multimedia streaming service is studied to avoid accessing through an external IP packet data network (IP-PDN) to streaming services. Under this scenario, the interaction(More)
1 Abstract DPLLs are used widely in communications systems. As a study of these devices, two DPLLs are designed and layed out in a 0.5um CMOS process. One is has a 30MHz starved inverter VCO, a programmable divider and a phase frequency detector. The second consists of a 400MHz differential inverter VCO, a fixed divider and an XOR phase detector. Both(More)
This paper describes a method for tracking the hands/arms of a person performing hand washing. A hand washing quality assessment system needs to know if the hands are joined or separated, if they are under water, if they are in contact with the towel or the tap, and it has to be robust to different lighting conditions, occlusions, reflections and changes in(More)
