Recent developments in intelligence surveillance camera systems have enabled more research on the detection, tracking, and recognition of humans. Such systems typically use visible light cameras and images, in which shadows make it difficult to detect and recognize the exact human area. Near-infrared (NIR) light cameras and thermal cameras are used to mitigate this problem. However, such instru...

Depth computation is an attractive feature in computer vision. The use of traditional perspective cameras for panoramic perception requires several images, most likely implying the use of several cameras or of a sensor with mobile elements. Moreover, misalignments can appear for non-static scenes. Omnidirectional cameras offer a much wider field of view (FOV) than perspective cameras, capture a...

Light-field imaging systems have received a lot of attention recently, especially with the release of Lytro cameras for consumer application. Conventional cameras capture 2D images, which are projections of a 3D scene. Light-field imaging systems capture not only the projection but also the directions of incoming lighting that project onto a sensor. Specifically, Lytro camara consist of an arra...

OBJECTIVE To obtain information on attitudes and experiences related to red light camera enforcement in cities with camera programs and in Houston, Texas, where cameras were removed after voters rejected the program in November 2010. METHODS Telephone surveys were conducted with 3111 drivers in 14 large cities (population greater than 200,000) with long-standing red light camera programs and ...

interactive 3-D media, structured light scanning, multiframe correspondence estimation, 3-D shape recovery, interactive view synthesis, view interpolation, active calibration The core to many 3-D related applications is establishing reliable dense correspondences among the multiple cameras used in a given imaging system. This paper proposes a structured light scanning technique for directly sol...

We present the design and implementation of a real-time, distributed light field camera. Our system allows multiple viewers to navigate virtual cameras in a dynamically changing light field that is captured in real-time. Our light field camera consists of 64 commodity video cameras that are connected to off-the-shelf computers. We employ a distributed rendering algorithm that allows us to overc...

Based on our experience in the DARPA Urban Challenge and on current trends in consumer automobiles, we believe that driver assistance systems can be significantly improved by new techniques in control and sensing that have been developed for fully-autonomous driving. In particular, from the control community, real-time Model Predictive Control (MPC) can be used as the next generation of cruise ...

Red light running is estimated to account for 900 intersection crash fatalities annually. Two principal methods used to reduce red light running involve lengthening the duration of yellow change intervals and automated red light enforcement. The present study evaluated the incremental effects on red light running of first lengthening yellow signal timing, followed by the introduction of red lig...
