In this paper, detection of pedestrian groups and counting of the number of pedestrians in each group using “subtraction stereo” are discussed. Subtraction stereo is a stereo vision method that focuses on the movement of objects to make a stereo camera robust and produces range images for moving regions. Pedestrian groups are detected with a standard labeling, and three dimensional (3D) feature...

A stereo vision based vehicle/obstacle detection system has been proposed that generates alarms when vehicles/obstacles are detected in vicinity of near/mid region. Numerous techniques have been applied to detect vehicles/obstacles using a forward facing monocular camera mounted inside a vehicle. This paper presents a methodology for vehicle/obstacle detection using high resolution stereo camer...

A different perspective to head tracking, one of the more studied topics in computer vision is presented here. The heavy reliance of contemporary head trackers on intensity images is countered here. The algorithm presented here, uses stereo data to track the head of a moving subject. This is used to achieve effective and accurate foreground segmentation. The head is modeled as an ellipse and tr...

Human stereo vision works by fusing a pair of perspective images with a purely horizontal parallax. Recent developments suggest that very few varieties of multiperspective stereo pairs exist. In this paper, we introduce a new stereo model, which we call epsilon stereo pairs, for fusing a broader class of multiperspective images. An epsilon stereo pair consists of two images with a slight vertic...

A driving support system developed for preventive safety purposes, such as a collision prevention system needs to have a method for detecting obstacles near the vehicle. A stereo-matching method using onvehicle cameras is expected to be the means of providing distance information (distance images) of higher resolution than radar. The conventional onvehicle stereo-matching method using the corre...
