Abstract: In complex outdoor environment, there are many limitations when using imaging processing algorithm. This paper proposes an adaptive vehicle extraction algorithm for real-time traffic surveillance system. In order to enhance the ability of adaptation to illumination changes, shadows and system noise in long-term running, the algorithm uses both morphological operation and edge histogram method to extract foreground vehicle objects. And it maintains certain accuracy and processing speed. Experiment on real-world video shows a rather satisfying result. Thus, this offers good foreground information for further vehicle tracking.
