title: OpenCV Image in Image Search (C++)
body: <p>I want to detect objects in a given "original Image", based on another "proposed Image". The "proposed Image" is  smaller than the original Image and it might not look 100% alike (background may differ slightly). I want to find all occurences of the "proposed Image" in the original Image. </p>
  
  <p>Is there an efficient way to do this in OpenCV?</p>
  
  <p>Thank you in advance!</p>
