An Adaptive Edge-Detection Method Based on the Canny Operator

On the basis of analyzing the conventional Canny algorithm, this paper advanced an adaptive edge-detection method based on the canny operator. This method not only keeps the Canny’s good performance in good detection, good localization and only one response to a single edge, but also improves the capability of restraining the fake edge and the automaticity of edge-detection based on the Otsu’s thresholding method. Through experiments, it is demonstrated that the adaptive edge-detection method in this paper is very effective.
