Оverlapping rectangles

I have a set of rectangles with weights, but some of them are overlapping in some region or entirely. I have make a function return the bounding rectangle, but in that case that the result is not so accurate and the result rectangle is way too big:

Now i have the weight of every rectangle. My question is whether is in opencv something, that can make the decision "Which rectangle is more important ?" and return something like that:

p.p. Now I'm reading about NMS (Non Maximum Suppression) but if there is something already implemented, why not to use it ;)

I doubt there's something in OpenCV for that, but why don't you do it yourself? It's fairly trivial:

Find overlapping rectangles and for each overlap, select the one with the higher weight.

Tonight I will think about it (with a beer or two) and tomorrow will try to implement it. ;]
