title: Accord.net haar object detection
body: <p>I'm trying to build robot arm which is capable of recognize trained objects. I know it can be done with opencv. But I'm not fluent in C++ programming. So I need to do it with C#. First I use Aforge.net and I recognize objects using color filtering, but it is poor method. So I found Accord.net has advanced techniques to do that. Haar feature object detection is one of that. I read the Accord.net documentation. It has a constructor</p>
  
  <pre><code>HaarCascade(Int32, Int32,HaarCascadeStage[])
  </code></pre>
  
  <p>first two integers are base width &amp; base height. What are them. What is stages? How to do it? </p>
