brightness in a neighborhood of size radius
around each pixel is compared to the average brightness of the
whole Image
, and the pixel value is scaled by the resulting
ratio. The radius
is specified in units of the
pixel size, and should be large compared to the size of the
features in the image, but small compared to the size of the image
itself.
