This work presents a new method to virtually recover ancient Chinese paintings in electronic form. Two factors result in the degradation of ancient Chinese paintings: pigment fading and paper aging. Thus, the proposed method first uses guided filter to enhance the original painting image. Then, the semi-transparent stroke as the image foreground can be extracted from the background of painting image by adopting a novel bi-extracting method. Two independent maps that respectively produced by the saliency detection and the pseudo-alpha matting are fused to represent the foreground stroke. Finally, the ancient painting image is recovered by altering the color of the background. Experiments on a variety of ancient Chinese paintings show the robustness and accuracy of the proposed method.
