Description of the data path
PIKE Technical Manual V3.1.0
117
• On the left you see the source image with non-uniform illumination.
• The surface plot on the right clearly shows a gradient of the brightness
(0: brightest Æ 255: darkest pixels).
• The histogram shows a wide band of gray values.
By defocusing the lens, high-frequency image data is removed from the
source image, therefore its not included in the shading image.
