title: Harris corner using Emgu CV
body: <p>Im trying to apply Harris corners using Emgu CV Wrapper, and I'm learning from a book titled "Open CV 2, Computer Vision Application Cook Book" , the book examples are based on C++, below is their example on Harris after replacing cv::Mat with it's equivalent on Emgu MCvMat, however that didn't compile so I used the "data" field on the MCvMat object, it did compile but it hangs, no error no exception but it just hang.</p>
  
  <pre><code> MCvMat cornerStrength = new MCvMat(); ;
   CvInvoke.cvCornerHarris(Global.GrayImage.Ptr, cornerStrength.data, 3, 3, 0.1);
  </code></pre>
  
  <p>any help will be appreciated</p>
