Rob Hess的SIFT代码

Contents: 1. Intro 2. Requirements 3. Running 4. License 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. /************************************************************************/ 4.
