The following figure respectively shows (a) original image, (b) and (c) two gradient images of the original image (a) (b) (c) Which among them depicts horizontal change in intensity (gradient along x-direction), and which one depicts vertical change in intensity (gradient along y-direction)? Select one: O (b) → gradient along y-direction, (c) → gradient along x-direction. O (b) → gradient along x-direction, (c) → gradient along x-direction. (b) → gradient along x-direction, (c)→ gradient along y-direction. O (b) → gradient along y-direction, (C) → gradient along y-direction.
