I've changed the calculation of orientation to something that I believe  is more stable. Oddly enough though the number of matched points in my  test pair have dropped. This can be rectified by lowering the surf  threshold in ipfind to .01 at the cost of spend more time calculating  the descriptor. Right now I think performance issues might be related to  my subpixel refinement.
