title: Detecting image translation with OpenCV
body: <p>I need to do a simple task: <strong>having a reference image, compute the translation in pixels of another images</strong> taking into account that there is <strong>no zoom</strong> and <strong>no rotation</strong>, just translation: (x, y). Having this, which is the easies method? autocorrelation? feature extraction? I guess feature extraction is not needed at all since it is a simple task.</p>
  
  <p>Any help would be appreciated,
  Cheers,</p>
