Abstract:

In order to restore the damaged image better, this paper proposes a new second total generalized variation based image inpainting model. By analysing the properties of new model, an efficient primal-dual algorithm is introduced. Experimental results show that the new model is better than the total variation model in terms of both peak signal to noise ratio(PSNR) and visual effect.

Key words: image inpainting, total generalized variation, total variation, primal-dual algorithm
