This paper involves object detection, object tracking and classification of objects, and indexing from vehicle surveillance videos automatically. The objects are detected using optical flow method and tracked using Kalman Filtering method. The objects extracted are classified using ten features including shape based features such as area, height, width,… (More)
In this paper, a vision-based real-time traffic analysis system is presented, which can analyze vehicles in traffic from a traffic video sequence. This paper discusses object detection, and tracking of objects in multiple video frames. The functionalities of traffic analysis using computer vision include vehicle speed estimation, traffic flow direction… (More)
Over a 12-year period, the authors encountered 2 patients with spinal axis/basimeningeal primitive neuroectodermal tumor (PNET) involving the spinal axis extramedullary, intradural compartment and the basimeninges. In neither patient was an intraaxial focus demonstrated. A 48-year-old woman had computed tomography (CT) findings of hydrocephalus and later… (More)
