A Novel Strategy for Visual Tracking and Visual Information Extraction

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 is extracted at the same time, such as the type and velocity of vehicle. An improved Fisher linear discriminate is proposed to extract the license plate. By experiments, this strategy is proved much effectively, and the accuracy of tracking is improved greatly.
