title: emgu finding image a in image b
body: <p>I'm new to emgu and would like some advice on where to start.</p>
  
  <p>I've looked through the shape detection but its far too complex for what i need .. i think.. and my surfexample isn't working. I get this error:</p>
  
  <p><a href="https://stackoverflow.com/questions/15643762/cannot-get-surf-example-in-emgu-cv-to-work">Cannot get SURF example in EMGU.CV to work?</a></p>
  
  <p>Anyway, this is what i would like to do: Find image A in image B. Image A is a simple square which always has the same grey 1 pixel border and always the same size (i believe) but the inner colour could be black or one of about 7 other colours (only ever a solid colour). i need to find the coordinates of image A in image b when i press a button. see the below images.</p>
  
  <blockquote>
    <p>Image <strong>B</strong></p>
    
    <p><img src="https://i.stack.imgur.com/rybjG.png" alt="image b"></p>
  </blockquote>
  
  <p>And</p>
  
  <blockquote>
    <p>Image <strong>A</strong></p>
    
    <p><img src="https://i.stack.imgur.com/HJ29C.png" alt="image a"></p>
