title: People Detection and Tracking
body: <p>I want to do pedestrian detection and tracking.</p>
  
  <p><strong>Input</strong>: Video Stream from CCTV camera.</p>
  
  <p><strong>Output</strong>: </p>
  
  <ol>
  <li>#(no of) people going from left to right</li>
  <li># people going from right to left</li>
  <li># No. of people in the middle</li>
  </ol>
  
  <p><strong>What have i done so far</strong>:
  For pedestrian detection I am using HOG and SVM. The detection is decent with high false positive rate. And its very slow as i am running in android platform.</p>
  
  <p><strong>Question:</strong>
   After detection how to do I calculate the required values listed above. <strong>Can anyone tell me what is the tracking algorithm I have to use and any good algorithm for pedestrian detection.</strong></p>
  
  <p>Or should I use tracking algorithm? Is there a way to do without it?</p>
  
  <p>Any references to codes/blogs/technical papers is appreciated.</p>
  
  <p>Platform: C++ &amp; OpenCV / android.</p>
  
  <p>--Thanks</p>
