• On the left you see the image after shading correction.
• The surface plot on the right clearly shows nearly no more gradient of
the brightness (0: brightest 255: darkest pixels). The remaining gra-
dient is related to the fact that the source image is lower than 50% on
the right hand side.
• The histogram shows a peak with very few different gray values.
