I want to know if a function that makes a such transformation exists in OpenCV :

Thanks for any help,

sorry, but your drawing does not explain anything. i also see no research from you at all here.

If your "transformation" preserves the curve length, just find a way to compute the curve length?

Thank you. I updated my drawing, I think the goal is more clear then. I want to exploit the green points. But the drawing is a simplification of a real case.

@berak : I didn't put research because I didn't find anything.

Maybe try to look at B├ęzier curve or B-spline and related topics if you want a mathematical basis.
