To find the image both horizontally and vertically. So, at first, to put windows in a horizontal brace on the left hand side of the image data. Then, the convolution function. (Convolution) weight in the window with the two-dimensional image data, the results are stored on the output. As a result, the window will move to the right hand pixels. And the Connecticut Revolution. Action will be like this indefinitely from left to right and from top to bottom until the picture. Figures The result is the image horizontally. Similarly, use The vertical windows in the convolution of the image data. Until the entire image is Vertical Edge When the image horizontally and vertically, and then to find the edges of the image by determining the size of the gradient, has the equation.
