说明： 所上载的为 Vedaldi 根据D. G. Lowe sift 算法编写的 MATLAB代码。尽管此网上有类似源码，但不同的是本附件代码已经经过本人编译，测试，可以直接运行。而且对sift.m中的一个BUG进行了修正（已通知到 Mr Vedaldi）。
(Uploaded for Vedaldi algorithm in accordance with DG Lowe sift prepared MATLAB code. While this line have similar source, but the difference is that the code of this Annex I have been compiling, testing, can be directly run. But also for sift.m a BUG amended (have been notified to Mr Vedaldi).)

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
0.9.10 Added sift_demo6.m.
0.9.9 Added a flag to compile on Intel Macs.
Improved the documentation.
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.
