%X The Canny edge detection algorithm which used Gaussian filter for smoothing the image may lead to lower SNR and higher edge location error, which produced false edge and corner roundness. To solve these problems, an improved edge detection algorithm was proposed by replacing Gaussian filter with anisotropic diffusion equations, and the image enhancement was carried out after diffusion. Experimental results show that the accuracy of edge detection is improved evidently, and a much better edge detection effect is obtained.
