title: C# image recognition
body: <p>I'm currently searching for a C# image recognition library.</p>
  
  <p>What I want to do: 
  I want to write a function that scans an image and returns if another image is part of it. Or at least something that looks familiar in case that the angles of the two objects are different.</p>
  
  <p>The link to a possible library and a short code example would be great!</p>
  
  <p>Thank you in advance!</p>
