title: SURF and SIFT Alternative Object Tracking Algorithm for Augmented Reality
body: <p>After asking <a href="https://stackoverflow.com/questions/1289010/using-sift-for-augmented-reality">here</a> and trying both SURF and SIFT, neither of them seams to be efficient enough to generate interest points fast enough to track a stream from the camera.</p>
  
  <p>SURF, for example, takes around 3 seconds to generate interest points for an image, that's way too slow to track a video coming from a web cam, and it'll be even worse when using it on a mobile phone.</p>
  
  <p>I just need an algorithm that tracks a certain area, its scale, tilt, etc.. and I can build on top of that.</p>
  
  <p>Thanks</p>
