SIFT algorithm in Matlab
I am looking for a Matlab implementation of the SIFT algorithm.
I'm not quite sure what you're after, but there are several MATLAB implementations of the SIFT algorithm available:
There's a demo executable available from David Lowe's page: http://www.cs.ubc.ca/~lowe/keypoints/
There are windows and linux executables for performing the SIFT extraction, and matlab functions for doing matching.
