title: How does VL_SIFT from vlfeat.org work?
body: <p>I am new to VLfeat implementation of SIFT in Matlab</p>
  
  <p>Could someone help/teach me more about how does VL_SIFT from vlfeat.org work? I have read the following link <a href="http://www.vlfeat.org/mdoc/vl_sift.html" rel="nofollow">http://www.vlfeat.org/mdoc/vl_sift.html</a> and this document <a href="http://www.cs.ubc.ca/~lowe/papers/ijcv04.pdf" rel="nofollow">http://www.cs.ubc.ca/~lowe/papers/ijcv04.pdf</a> but I still do not understand how it works.</p>
  
  <p>Thanks
