Abstract: Digital rubbing is a new approach to inherit rubbings art.The key of digital rubbings is how to solve the uneven illumination of stone images and black background,to generate ideal images that can not only full reflect target images and details,but also have the basic characteristics of the rubbings in the process of making digital rubbings.Through specific examples,this paper analyzed the basis for confirming the key technology of digital rubbings.The experiment results show that these key technologies have solved the above problems properly and produced ideal digital rubbings.

Key words: Digital rubbing,Average filtering,Partial threshold,Image fusion
