Abstract: A new nonlinear multigrid (NM) method is constructed by setting effective restriction operator and interpolation operator for differential curvature,and this method is applied to TVP model based on differential curvature.The experimental results show that the peak signal-to-noise ratio (PSNR) of images processed by the new method is significantly higher than that of the fixed point iteration (FP) method,and the convergence speed is 2~3 times that of the fixed point iteration method.

Key words: image denoising, nonlinear multigrid method, restriction operator, interpolation operator, TVP model
