Exposure correction: White balancing & GammaCorrection
I am trying to solve this problem : there is a set of pictures all off them have ColorChecker chart(you will find an example below). i already created a program that extract all the patchs of the ColorChecker chart ( i am more interested in the 6 gray patches; from white to black). My goal is based on one of the ColorChecker chart from one of the images of my choice(the one i think it has the best exposure), i want to apply a correcrtion ( gamma correction , white balance, exposure compensation.. i really don't know which one and how to do any of them) on the rest of the images so that at end all the gray patchs in every single images have the same RGB value.
cheers, Zouhair
