I was taking a look at the histogram calculation function in this tutorial code ..> http://docs.opencv.org/doc/tutorials/...

At the end of the program, they have used a function normalize( ). My question is, what does normalization do exactly? and what is it's specific purpose in this example?

do you recall , what a 'unit vector' is (in 2d or 3d) ? it's basically the same idea
