On the basis of full consideration of the complexity of coloring and abundance of lines in the Dunhuang murals and the difficulty to find their source images with similar texture,the Dunhuang murals,the color of which was changed due to chemical reaction in their pigment,were segmented,automatically gathered for data,transferred with coloring by means of GrabCut algorithm and finally recovered.The detailed procedure was as follows: firstly,the discolored and faded parts of Dunhuang murals were segmented with GrabCut algorithm;secondly,the color data of painted parts without fading was selected as source images and their colors were transferred onto the segmented images.The experimental result showed that a combined method of GrabCut algorithm with automatic color gathering and transferring was suitable to recover the discolored Dunhuang murals,and the recovering result was satisfactory.
