In this paper, we suggest a new processing algorithm based on anisotropic diffusion and nonlinear process for removing noise and image enhancement. The principle of the proposed algorithm is to apply a Gaussian filter to the image gradient when computing the diffusion coefficient and to choose the gradient threshold parameter depending on the gradient of the image at each iteration in the model adopted by
