Other highly recommended Computer Vision software sites

• Andrew Zisserman's MATLAB Functions for Multiple View Geometry

• Jean-Yves Bouguet's MATLAB Calibration Software

• MatlabBGL David Gleich's MATLAB Graph Library. This fills a big hole in the MATLAB standard packages.

• VLFeat by Andrea Vedaldi and Brian Fulkerson is a excellent library of vision algorithms. Here you will find SIFT, MSER, k-means and more. All beautifully documented.

• Piotr's Image & Video Toolbox for Matlab maintained by Piotr Dollar and Vincent Rabaud. Well documented functions for filtering, clustering, classifying and more.

• Peter Corke's Machine Vision Toolbox he also has a well regarded Robotics Toolbox.

• Libor Masek's Iris Recognition Code

• Epipolar Geometry Toolbox by Gian Luca Mariottini and Domenico Prattichizzo.

• MathWorks' links to sites containing MATLAB vision functions

• Samuel Albrecht has produced a GIMP Octave Plugin which makes Octave scripts executable from inside GIMP.
  You can download the plugin (and some of my functions that he has had to modify slightly) from
  https://sites.google.com/site/elsamuko/gimp/gimp-octave or from
