The proposed method can automatically set the threshold value according to the different image gray-scale gradient histogram adaptively and improve the performance in the detail edge detection and good localization. Experiments show that this method produces better edge detection results performance than the Otsu method. Besides our method  Roberts operator  Prewitt operator  Sobel operator  Log operator and Canny operator based on Otsu algorithm are also tested for comparisons.
