Inpainting of Potala Palace murals based on sparse representation

Murals in Potala Palace is one of the world cultural heritage, in order to protect and spread the cultural relics better, it need to be informatization and inpainting by modern computer technology urgently. A novel model of inpainting the Murals is proposed, which carry on the dictionary learning by MOD algorithm, and filling missing pixels by known pixels in sparse domain, so as to implement the inpainting of murals and remove impulsive noise. The experimental results show that the algorithm can inpaint the image more effectively and decrease the RMSE, this method has better performance than other dictionary learning algorithm, and has good application potential and good application prospects.
