title: Finding Sub-Images in a image
body: <p>I have a fairly simple situation. I just don't know any specific terms to search for.
  I have a single image, in that image I have several other images that follow a basic pattern.
  They are rectangles and will possibly have landmark image to base things off of.
  An important part, is that I need to detect rotated/mis-scaled sub-images. </p>
  
  <p>Basically what I need to be able to do is split 'business cards' from a single image into properly aligned single images.</p>
  
  <p>As I am also designing the cards to be scanned I can put in whatever symbol or something that would make detection easier (as I said a landmark)</p>
