Recognition of Pavement Image with Shadow Based on Image Decomposition

In the process of collecting the pavement images, there exists shadows in the pavement images due to various objects on the road and rodside. This seriously affects the auto-identification and classification of the images. In view of this problem, we propose a recognition method which can deal with the shadow. We withdraw the edge subset of the shadow in the image by image division and decompose the image into the light part and shadow part. Then the two sub-images can be classified by the variance of the sub-images. This method is simple, and avoids disturbance of the shadow. The availability of the method has been proven by the experiment's results.
