Description: Sobel operator (Sobel operator) operator is one of image processing, mainly for edge detection. Technically, it is a discrete difference operator for the operation gradient approximation image brightness function. At any point using this image operator, will have its corresponding gradient vector or vector method Sobel operator has two, one is to detect the horizontal edge the other is to detect vertical flat edge. Sobel operator is another form of isotropic Sobel (Isotropic Sobel) operator, there are two, one is to detect the horizontal edge, and the other vertical edge detection isotropic Sobel operator Sobel operator and ordinary compared to its location more accurate weighting factor, consistent detect edges in different directions when the magnitude of the gradient. Due to the special nature of the building of the image, we can see that, when dealing with this type of image contour, gradient direction does not need to be operational, so the program does not give an isotropic Sobe
