There are 2 images loaded into 2 seperate labels
The user identifies(clicks) 3 points in the 1st image
and identifies 3 points in the second image similar to the 1st image.

I want to calculate the amount of rotation needed and translation needed for the points to be alligned
(I'll probably have to calculate the average rotation of each point before i rotate image 2 to allign with image 1) ->ideas

I know more or less how to do it using matrices and some functionaltiy in opencv...
But since I cant get opencv to operate in my windows qt environment

Is there a way around it?
Other Ideas on this matter

Thank you
