Abstract: In view of the limitation of the existing methods, a new algorithm of background extraction and updating was proposed. The interval pixel value belonging to the video stream was calculated to extract background. The edge detection method was referred to analyze the area of continuous change when there was stagnant vehicle in the current background image. The testing results demonstrate that the proposed method can be well adapted to the application of the complicated situation with markedly improved accuracy, and it is simple and suitable for real-time detection.

Key words: background extraction, background updating, interval distribution, edge detection, vehicle detection
