Hi,
This patch was part of GSoC Color Constancy filter. It introduces an
improved color constancy filter(weighted_greyedge) based on the already
pushed greyedge. I'm sending it again after updating it against latest
version of master.

Mina Sami

No need to Cc people who are on the list.
Actually replied only to you initially, sorry about that.

I haven't received any feedback regarding this qualification task

I thought I was ask for any reviews about my task so that I can fix it
if anything needs fixing. Thanks in advance.
