(a) Location of the split scene image with GIF was at a size of 2 km × 2 km for the first-stage split scene image in the scene image data . (b) Location of the split scene image with GIF for the second-stage split scene image in the scene image data . (c) The coefficient of variation value on the first-stage split scene image can be plotted on the X-axis, and the scene ratio value can be plotted on the Y-axis. (d) Plot of the second-stage split scene image for the coefficient of variation value on the X-axis and the ratio of the scene value on the Y-axis.
