Abstract: A algorithm is developed for counting vehicles. The approach includes calculating and updating the background image correctly, extracting the vehicle regions with a self-adaptive threshold, removing the shadows, segmenting different vehicles, determining the vehicle number when the centers of vehicle regions are matched in several uninterrupted images. This algorithm is not affected by divided roadways, and it also can diminish the man-made mistakes. Experimental results demonstrated that the algorithm can count the vehicles accurately in an outdoor circumstance.

Key words: background subtraction, shadow removal, flow measuring, seriate images processing
