title: SimpleBlobDetector not found in opencv 3.0 for python
body: <p>I am trying to use SimpleBlobDetector in python with cv2 version 3.0.
  However when I run:</p>
  
  <pre><code>import cv2
  detector = cv2.SimpleBlobDetector()
  </code></pre>
  
  <p>The console returns me:</p>
  
  <pre><code>AttributeError: 'module' object has no attribute 'SimpleBlobDetector'
  </code></pre>
  
  <p>Does anyone know if the function name has changed from cv2 version 2.4 to version 3.0?</p>
