title: Count people standing in front of our Kinect
body: <p>We are making an interactive installation with a Kinect, and we need to know how many people are standing / walking slowly in front of our installation.</p>
  
  <p>We will count up to 5 people, if there is more we don't care.</p>
  
  <p>To do that we take the total volume of blobs detected by the Kinect, divide it by the approximative volume of 1 person.</p>
  
  <pre><code>count = Vtotal / Vperson;
  </code></pre>
  
  <p>Finally, to smoothen the count, we calculate the average count on 2 seconds.</p>
  
  <pre><code>countAvg = Vtotalavg / Vperson;
  </code></pre>
  
  <p>This works OK-ish for 2-3 people, but when there is more, the blobs overlap, and the total volume doesn't seem to be relevant anymore.</p>
  
  <p>Does somebody have an idea how we could solve this and have a reliable count ... either by using the same blob volume method, or something smarter !?</p>
