title: Object tracking using android
body: <p><p>I want to create an android app where a live camera stream captures obstacles on the ground and issues warnings to the user. This is intended as an application for the visually impaired.  </p>
  
  <p><p>I'm at a loss to understand what technologies are most suitable for this as I have no previous experience in image processing. I looked through some OpenCV examples, but they didn't provide me with much insight as to where to start the project from.  </p>
  
  <p><p>What I need to know is;</p>
  
  <ul>
  <li>Any tutorials that might help me to get started on the project (should I start with basic image processing?)</li>
  <li>Should I learn C++, since I only know java and C#?</li>
  <li>What technologies that could be used in the project. (Is it possible to achieve something like this through Augmented Reality etc..)</li>
  <li>Any previous projects/ tutorials/ examples that tries to achieve android image processing</li>
  </ul>
  
  <p><p>If you could provide me with some answers to any of the above points I'd be much grateful. </p>
