@berak I'm not able to find out what is missing in the function alignContour

maybe the center-of-gravity is the wrong measure here ?

imagine a spoon, the COG will be somewhere in the bowl, with a large handle protruding from that.

unsure, if i misunderstand you, but i'd rather try with the "geometric center" (the center of the contour's boundingBox) here

I'm going to go out on a limb here and guess it's because you don't have any code that even attempts to find the center of gravity. Fortunately for you, OpenCV has a function for just that. Moments. As a matter of fact, just about everything you need should be on that page.
