What the function calcHist() give us

What the function calcHist() give us

My question is when we normalize the histogram , is there any build-in
function for that , if not than obviously we can calculate the histogram
of the image using the function calcHist() , but the formula of
normalizing histogram is Nk/N so what calcHist return us is N in this
formula , or we have to calculate N on our own , and whats its role in
entropy formula
