为更好地修复图像, 提出了一种新的基于二阶总广义变分的图像修复模型. 通过分析新模型的性质,给出了一种有效的原始对偶修复算法. 实验结果表明, 相比于总变分图像修复模型, 提出的新模型在修复结果上有更高的峰值信噪比和更好的视觉效果.
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.
