说明： sift图像匹配的纯matlab代码,研究图像配准的可以用这个，配准图像效果较好！！
(sift pure image matching matlab code of image registration can use this, the image registration is better! !)

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
From MATLAB prompt
> sift_compile
From shell prompt (Linux, Mac OS X)
> make
TESTING
> sift_demo
> sift_demo2
> sift_demo3
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
0.9.8 Minor bug fixes
0.9.7 Fixed a minor glitch in the convolution code. Increased the
default number of octaves that get computed (this is more
similar to Lowe's version).
0.9.6 Modified the convolution code to handle image boundaries more
similarly to Lowe's version.
0.9.5 Fixed a minor issues with the new sift_demo3.m.
0.9.4 Fixed another bug in the detection of keypoints close to
the boundary. Reduced the size of the distribution. New test code.
0.9.3 Improved plotmatches.m and tightsubplot.m
0.9.2 Improved detection 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.
