Fig. 5.23 shows the application of the Region-LUT to a camera image. The original image
without image processing is shown on the left-hand side. The result of the application of the
Region-LUT is shown on the right-hand side. One Region-LUT was applied on a small region on
the lower part of the image where the brightness has been increased.
