Hi,

Thank you for the response.  I have uploaded the images in the below
link.
http://groups.google.com/group/aforge/web/WB-Levels-BeforeAfter.jpeg
I have to compare the images and output the result as  which of the
images
has the  correct white balance. In the pictures in the above link we
can see the
second image looks more natural.   Ofcourse manually we can see both
images
and say which of them is better. Similarly i compare the luminosity of
the two images
and say which one is brighter picture.  Hope this is clear.

Thanks
Rajani
