Module used for white balancing adaptation of a color image. Given a reference image
area and a target color, for example a white part of the input image and the color coordinates
for white, applies von Kries adaptation to the image. This will transform the reference area
the target color and simultaneously change the color coordinates for all other pixels in the
image. The image region for the reference color is given by x0, y0, x1, and y1 and the color
of the reference region is given by red_target, green_target and blue_target. In addition,
the average color of an arbitrary region can be written to the output, This region is set by
the log-parameters.
The reference region can only be set in the XML-file and can not change during execution.
This should be changed in the future with either an adaptive white calcuation or an attention
based method.
