Aim to problems of traditional canny operator, we propose an improved canny edge detection method. First, in order to overcome excessive smoothing, we use multiwave adaptive denoising method to instead of Gaussian filter. Then after obtaining non-maxima suppression image, we use mean values of gradient of entire image to adaptively select dual-threshold to instead of manually setting threshold. Our experiments are conducted on original image and noise image respectively. Experiments show compared with other traditional methods, this method can effectively remove noise, reduce the occurrence of pseudo-edge and obtain a more ideal edge detection effect finally.
