We present a method to detect and recognize functional scene elements in video scenes. A functional scene element is a location or object that is primarily defined by its specific function or purpose, rather than its appearance or shape. Our method combines techniques from video scene analysis with functional recognition to decompose a video scene into its functional elements such as parking spots,...
Vehicle tracking is an essential requirement of any vision based Intelligent Transportation System for extracting different traffic parameters, efficiently. Handling inter-object occlusion is the most challenging part of tracking as a process of finding and following interested objects in a sequence of video frames. In this paper we present a system, based on code-book background model for motion...
In order to improve the precision and real-time character of the traditional video-based traffic detector, a novel vehicle detection system based on line scan camera is developed. In this system, the vertical view images of vehicles are captured by two line scan cameras which are mounted on the pole's arm over the roadway; The distance between two cameras is 2 meters along the road. The vehicle's...
Location detection method based on vision of motional vehicle is studied in this paper. Conventional method is frame difference method, which is realized by contrasting the different of sequential two frames of vehicle image, and which is easy to detect the background of current frame sheltered by previous frame. Second-difference algorithm is improved in the text, which is the improved algorithm...
Most approaches to vehicle tracking have adopted a single calibrated camera for the task, which leads to an under-conditioned problem. We present a surveillance system for on-line vehicle tracking based on two cameras and structure from motion (SfM). Our surveillance system starts by tracking feature points. A novel matching scheme is proposed that allows a subset of feature points to be corresponded...
In many areas of the world, overhead video collected from aircraft and other airborne vehicles is an important component of surveillance and security operations. A typical use scenario might involve real-time monitoring of video streams by human analysts with the goal of identifying patterns of vehicle movement that might be considered suspicious or dangerous. In performing such a task, analysts often...
A novel strategy for the visual tracking and the information extracted problem is proposed which is for the case of maneuvering target. The strategy contains two methods. One is used to tracking, and the other one is used to extract the information of the vehicle. A non-linear estimation method using the particle filter to track objects is presented. During the tracking, a great deal of vehicle information...
An image-based technique with high measurement rate has been proposed to measure the distance between two moving vehicles. By combining several near-infrared (NIR) LED markers mounted on the forward vehicle with an NIR-filtered CMOS camera mounted on the backward vehicle, one can clearly recognize the marker shape and positions without any adjusting the focus lens of camera, and hence he can extremely...
The automatic lane marking detection, vehicle detection and incident detection systems are proposed in this paper. The block-based background extraction that combines statistical algorithm and the moving block information is used to obtain the color background image more exactly. The lane detection algorithm is applied to obtain the lane information from the color background image without the limitation...
