In this paper, the theory and mathematical properties of the nonlinear diffusion methods was introduced and a overview of the different algorithms in image processing was gives. At last, the tendency and open problems of nonlinear diffusion was pointed out the from the aspects including the contradictions of image denoising and feature preserving, clos-ing of structures, preservation of discontinuities and parameter simplification.
