说明: SIFT算法,可以有效的找到不同画面中的对应特征点,在跟踪和图形识别方面有很好的用途
(SIFT algorithm, can effectively find a different screen the corresponding feature points, in the tracking and pattern recognition as a very good use of)

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
0.9.2 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.
