title: slow kd-tree queries using vlfeat, faster alternatives?
body: <p>I'm using vlfeat's kdtree which implements the kd-tree from FLANN, which supposedly handles high dimension data. However, right now I have a kdtree built from a 128x15000 set of data and kd tree queries for anything has slowed down to 8 seconds a query. Is this the limit of kd-trees? FLANN was supposed to be a faster optimized kdtree too...</p>
  
  <p>what other options do I have now?</p>
