An Improved CANNY Edge Detection Algorithm

Canny arithmetic operator has been proved to have good detective effect in the common usage of edge detection. However, Canny operator also has certain deficiencies. Based on the analysis of the traditional Canny algorithm, an improved Canny algorithm is proposed in this paper. In the algorithm, self-adaptive filter is used to replace the Gaussian filter, morphological thinning is adopted to thin the edge and morphological operator is used to achieved the refining treatment of edge points detection and the single pixel level edge. The results of experiment show the improved Canny algorithm is reasonable.
