%X Linear filtering used for smoothing the image before the edge detection may lead to blurry edge and higher edge location error. To solve these problems, this paper proposed two kinds of nonlinear filtering such as anisotropic diffusion filtering and bilateral filtering, also, applied them to edge detection respectively, by contrastable experiment results indicate that the rate of accuracy of edge detection can be enhanced and a much better edge detection effect is obtained.
