title: Pattern matching matlab
body: <p>I was a student, has just begun the matlab
  Matlab would like to ask, I hope someone can answer</p>
  
  <p>Now there are three images are A, B, C
  b is a diagram capture down on a small area, it may be a solid color block, c is high similarity with a graph picture may be some position moves slightly changed,</p>
  
  <p>How to use matlab to compare and identify the relative position of the b Figure c Figure :( ?
  Such as coordinates or marked.</p>
