USAGE

---

This code requires MATLAB and the Image Processing Toolbox. It was tested with MATLAB Version 7.7 (R2008b) and Image Processing Toolbox Version 6.2 (R2008b). However, it makes very little use of the Image Processing Toolbox and should be easy to modify to work without this toolbox.

To use this software:

    run matlab 
    cd to the directory containing this code 
    run one of the functions with the name V1_*

Each of the V1_* functions runs one of the experiments reported in the above publication. The following table gives details of which MATLAB function produces each figure in this article.
