Abstract
An image processing method for conducting anisotropic diffusion filtering on a pixel value Iin a two-dimensional image, comprises: finding conduction coefficients C, C, C, C, C, C, Cand Cin eight surrounding directions for each pixel based on a pixel value gradient ∇I to produce a two-dimensional distribution image of the conduction coefficients; and finding pixel value first partial differentials ∇I, ∇I, ∇I, ∇I, ∇I, ∇I, ∇I and ∇I in the eight surrounding directions for each pixel to calculate a pixel value in an output image according to:
