Adaptive Vehicle Shadow Detection Algorithm in Highway

Traditional shadow suppression method based on HSV color space was proved to be an effective method. However, shadow detection with fixed parameters does not meet the change of monitored scene. According to vehicle property and scene change by the shadow projection, this article proposed an adaptive detection algorithm to achieve proposes of adaptive shadow suppression without adjusts the threshold manually. Experiment result shows that, in the process of monitoring and tracking on the highway, this method can adaptively suppress the shadow in the condition of the scene change.
