AN IMPLEMENTATION OF LOWE'S SCALE INVARIANT FEATURE TRANSFORM Andrea Vedaldi vedaldi@cs.ucla.edu http://www.cs.ucla.edu/~vedaldi/ This is a MATLAB/C implementation of the SIFT detector and descriptor [1]. See the documentation in 'doc/' to get started. COMPLING AND TESTING From MATLAB prompt > sift_compile > sift_demo > sift_demo2 From shell prompt (Linux, Mac OS X) > make ABOUT 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 0.9.3 Improved plotmatches.m and tightsubplot.m 0.9.2 Improved selection of keypoints too close to the boundary 0.9.1 Fixed a bug in the creation of the .zip archive 0.9 Fixed a bug for which some of the keypoint detected where dropped. CREDITS The SIFT algorithm [1] has been patented by David Lowe. Some of the images in 'data/' are from [2,3]. [1] D. G.
