Some modifications by Vadim:

  46  /*  
  47   the following changes have been made, comparing to the original contribution:  
  48   1. A lot of small optimizations, less memory allocations, got rid of global buffers  
  49   2. reversed Order of cvgetquadranglesubpix and cvresize CILS; probably less accurate, but much faster  
  50   3. the descriptor computing part (which is most expensive) is threaded using OpenMP  
  51   (subpixel-accurate keypoint Localization and scale estimation are still TBD)
