body: <p>Actually I want to use "estimated Geometric transform" matlab's function in opencv c++, is their any kind of such function which works exactly same in opencv in c++?</p>
  
  <p><a href="https://www.mathworks.com/help/vision/ref/estimategeometrictransform.html" rel="nofollow noreferrer">Matlab function</a></p>
