title: Warp an image into a quad region of another image using OpenCV
body: <p>I have an image and i know four coordinates of that image, now i just want to put another small image on the contour formed by these four points. This contour is almost a square.
  Is there a way to fill this contour points with the image?</p>
  
  <p>I tried to create a rectangle but i can't create a rectangle using more than one point.
  I'm stuck. Can't find any solutions.</p>
