title: Haar cascade for face detection xml file code explanation OpenCV
body: <p>I am performing face detection using opencv haar cascade.</p>
  
  <p>I wanted to know the explanation of the xml code of the haar cascade that I have included in my program. Can someone help me to understand the values presented in the XML file, for instance: <code>weakcount</code>, <code>maxcount</code>, <code>threshold</code>, <code>internal nodes</code>, <code>leaf values</code> etc. </p>
  
  <p>I have made use of the <code>haarcascade_frontalface_alt2.xml</code> file. I have already performed face detection. Currently I am working on counting the number of faces detected. </p>
