  Moving object detection is the basis for reliable high level processing such as object tracking and action recognition. Shadow verification processes are very important to ensure integrality of extracted moving objects. Moving features appear in detected shadow regions indicate classification errors. The proposed method identifies false detected shadows by detecting moving features and corrects those classification errors by means of image matting operated on candidate shadow regions. Existing approaches for image matting require manual labeling of foreground and background. We propose an automatic scribbling method followed by a closed-form matting process to solve the coefficient alpha. Then, the alpha image is binarized directly to avoid time-consuming computation for reconstructing foreground. Experiments demonstrate that our method can improve the moving object segmentation effectively even in the case of object parts and shadows presenting similar characteristics.
