This paper applies Total Variational(TV) model to inpaint image,proposes an optimization transformation method for image inpainting.It uses an optimization transformation technique which involves replacing their univariate functional of TV model by a bivariate functional by adding an auxiliary variable.The Chambolle's projection algorithm and alternating minimization method are employed in solving the model.Experimental results show that compared with the algorithm of solving TV model based on gradient descent method,the efficiency and quality of inpainted images by the proposed method is improved.
