A SIFT IMPLEMENTATION                            Andrea Vedaldi                         vedaldi@cs.ucla.eduThis is a MATLAB/C implementation of the SIFT detector and descriptor[1]. See the documentation in 'doc/' to get started.CREDITS  The SIFT algorithm [1] has been patented by Dr. Lowe. Some of the  images in 'data/' are from [2,3].COMPLING AND TESTING  From MATLAB prompt  > sift_compile  > sift_demo  > sift_demo2  From shell propmt (Linux, Mac OS X)  > makeABOUT THE SOURCE CODE  We use the follwing convention to name files:  *.m *.c:       M and MEX files  sift*mx.c:     `Private' MEX files   sift_*.m:      Service scripts (compiling, demos)CHANGES  0.9   Fixed a bug for which some of the keypoint detected where        dropped.REFERENCES[1] D.
