Vehicle tracking system using compare background vector weight

An image tracking method using a movement weighted value and a background image estimation comparing scheme is provided to exactly obtain a vehicle image by comparing movement information with a vector compensation coefficient of a background image. After images are input through cameras, a preprocessing is performed(1). A movement weighted value is estimated through the preprocessing(2,3). A moving object is extracted from a background image. The movement weighted value is applied(4~7). The moving object is determined by using a threshold value. A labeling is performed to track a next image(8). A shadow is removed from the background image through the movement weighted value and a singular point analysis of the moving object based on the threshold value(9~11). The shadow is removed based on the size and type of a vehicle(16,17). An exact shape of the vehicle is obtained through readjustment of images(19).
