Hi guys,
I am just here for giving a suggestion to OpenCV developers.
First of all, look at this photo details: link text
Color profile is not just for printer and monitor anymore. In these days, lot's of professional photographers are dealing with ICC/ICM color profile to make custom color tone shift easily. All they need to do with it is just embeding a ICM file to an image file and that's all. ICM file itself contains all color tone shift information in it. You should check the link above, and make it available within OpenCV users.
Thanks,
