SIFT Feature Detection library Copyright (C) 2004, Sebastian Nowozin (nowozin@cs.tu-berlin.de) Version 1.8 README file Introduction ============ The SIFT feature detection algorithm has been invented and published by David Lowe at the University of British Columbia. A detailed account of the complete algorithm is available at http://www.cs.ubc.ca/~lowe/papers/ijcv03-abs.html The algorithm provides the capability to identify key feature points within arbitrary images. It further extracts highly distinct information for each such point and allows to characterize the point invariant to a number of modifications to the image. It is invariant to contrast/brightness changes, to rotation, scaling and partially invariant to other kinds of transformations. The algorithm can be flexibly used to create input data for image matching, object identification and other computer vision related algorithms. This package provides an implementation of the SIFT algorithm as library. License ======= The license for this package is available in the "LICENSE" file. The SIFT algorithm is patented in the United States and as such restricted in use. For details, refer to the LICENSE file. Installation ============ You need a .NET Framework implementation, I prefer Mono. - Mono (http://www.go-mono.com/) 1.0 or later - GTK# (http://gtk-sharp.sf.net/) 1.0 or later. - GNU make, GNU bash. Under Unix they should be already installed, under Windows you might need CygWin (http://www.cygwin.com/) Sorry about introducing this dependancy-bloat, but I hope in the future every system will have a .NET Framework installed, preferably mono :). Under Debian/sid you can install the "mono" and "libgtk-cil" packages. In the "libsift" package, you can only build the "lib" target: make clean lib You cannot use any other target. Development =========== The best starting point to use this library is to download the "autopano-sift" package, which is available from http://cs.tu-berlin.de/~nowozin/autopano-sift/ It includes a large number of programs using this library. If you have any questions, please send me email. Further improved and fixed versions of this package may be available at http://cs.tu-berlin.de/~nowozin/libsift/ Please send me patches, fixes and comments for this implementation, I would be glad to hear them. See the TODO file for cues what needs to be improved. Contact ======= I can be reached through this email: nowozin@cs.tu-berlin.de
