Abstract: A nocturnal vehicle counting method based on a mixed particle filter is introduced in that, in a nocturnal environment, a rear lamp of a vehicle is the most remarkable feature of the vehicle and forms a high-brightness region of an image of the vehicle. The method involves detecting the high-brightness region of an image of the vehicle to thereby detect the rear lamp of the vehicle. The method further involves operating a particle filter structure which, coupled with the detection of a moving high-brightness region, can detect and track the rear lamp of the vehicle simultaneously, thereby enhancing competitiveness and incurring low costs.
