利用非局部算子的定义,提出了一种新的非局部扩散的修复模型.该模型在扩散的过程中充分利用了图像的全局信息对损坏的区域进行修复,克服了偏微分方程模型在修复图像时产生的模糊和不能很好地保护图像边缘及纹理的不足.实验结果表明,该模型是行之有效的.
We present a new inpainting model of nonlinear diffusion using the definitions of nonlocal operators.This model can inpaint those damaged domains by making use of the image global information.Furthermore,it can overcome the shortcomings that PDE can lead to some blur in diffusion procession and cannot preserve the edges of the image better.Experimental results show that this new model is feasible.
