1. Intro
This is a collection of code I've put together to detect SIFT features in
images. It includes a SIFT function library as well as some executables
to detect, match, and display keypoints. For more information on SIFT,
refer to the paper by Lowe:
Lowe, D. Distinctive image features from scale-invariant keypoints.
International Journal of Computer Vision, 60, 2 (2004), pp.91--110.
Or see Lowe's website:
http://www.cs.ubc.ca/~lowe/keypoints/
Some of the code also works with affine-invariant features from the code
by the VGG at oxford:
http://www.robots.ox.ac.uk:5000/~vgg/research/affine/index.html
Also included is a library containing functions to compute transforms from
image features using RANSAC. See match.c for an example of how to use
the RANSAC functions.
/************************************************************************/
2. Requirements
All code in this package requires the OpenCV library (known working
version is 1.0.0):
http://sourceforge.net/projects/opencvlibrary/
Some functions require the Gnu Scientific Library (GSL) (known working
version is 1.8):
(Linux) http://www.gnu.org/software/gsl/
(Windows) http://gnuwin32.sourceforge.net/packages/gsl.htm
/************************************************************************/
3. Running
The following is a list of directories that contain VC++.NET projects
and the functions of the projects:
*siftFeat -- Detect SIFT features
*match -- Find and match SIFT features in two images
*dspFeat -- Display features from a file
You can mess with the global variables in each of the main C files to
adjust parameters, including input and output files. You might also have
to adjust the project properties depending on how you installed OpenCV
and GSL.

Columbia. Thus, the SIFT feature detection code in this package may not
be used in any commercial products without permission from UBC. All other

温馨提示
比较经典的sift-1.1.1_20070330_win版本,适合win32平台。不过必须openCV支持。
