Gradient of the image is available from the difference of the level of gray pixels around the x axis and y axis in which the Gradient of a 2D, I (x, y) can be described in terms of the vector as follows:
Gradient of images obtained from The difference of the gray level of the pixels around in both the x and y axes, which Gradient of 2D, I (x, y) can be described as the vector as follows.
Gradient of images obtained from the difference of the gray level of pixels around the core and core y X which Gradient picture 2D I (,, x y). Can be explained in terms of vector as follows.
