Figure 2
The gradient magnitudes for the image in (a) are shown in (b). The darkest points here correspond to the steepest gradient. The direction of the gradient at each point is shown in (c), where the direction is plotted as an angle between 0 and 360°. The sharp change from black to white seen along the edge of the drop is merely owing to the change in angle between 0 and 360°. |
