title: Achieving heat vision in OpenCV
body: <p>I am doing a project and my professor said "try to use heat vision as well". I am doing the whole project in OpenCV, and no way of dropping it.</p>
  
  <p>I have no idea about how to do heat vision. I got only $50-$70 to spend for any device because rest is spent for other devices I am using. </p>
  
  <p>So my question is, how to do heat vision? I am now identifying human using OpenCV with the help of videos captured by a normal webcam but heat vision also suggested by professor. Is there any way of doing heat vision in OpenCV? What kind of cjeap device do I need? Device should have a C# or C++ api as well.</p>
