I am working on a project and I need to perform white balancing on the images. I am using opencv 2.4.10. Is there any built-in functionality in opencv to do white balancing? I searched on the internet but could not find any. If not, can anyone please guide me how this can be achieved?

Apparently you did not search that hard :-p, but that's ok. There is a new function that you can find at the contribution repository. Check here for documentation and here for a sample. Moreover, you can also have a look here if you want to get an idea how to implement it by yourself.

just saying, - xphoto (like anything from opencv_contrib) will require opencv3.0

@theodore: The function is in Opencv 3.0. Is there something similar in opencv 2.4.10?

@aries currently there is not. So, you have three options either you download the git version of opencv 3.0 and you compile it with the opencv_contrib modules enabled and then use it, if you do not want to do that another option is to just adapt the function from the source file which you can find here and integrate it in your code, or your last option is to just follow the the code in the tutorial that I submitted in the last link of my answer.
