i am doing project using opencv on raspberian wheezy (Linux) platform.Can anyone provide me a code for histogram equalisation using python language.

edit

I have two images, one source and one target. I want to get the histograms of both source and target. Finally match the histogram of target wrt source. The opnenCv method 'equalizeHist' does it for one single image. Is there a way to do it with two images??
