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 2.0):
http://sourceforge.net/projects/opencvlibrary/
/************************************************************************/
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.
