A Unifying Framework for Mutual Information MEthods for use in
Non-linear Optimisation.

N Dowson and R Bowden



This directory holds the binaries and scripts for tests performed when
writing the paper of the above title. 

There are 3 binaries:
* mexMImsr - for measuring a the similarity between a warped template
             and an image using either Sum of squared differences,
             Normalised Correlation or Mutaual Information (std/pve/ipz).
* mexMIopt - Tries to find the warp that minimises (or maximises) the
             above functions for the given reference and template image 
             pair.
* mexMIx   - Extracts a warped region from and image.

For more details just type the binary name at the matlab prompt and an
explanatory error messge should appear. Unfortunately only linux
versions of these binaries are available. These binaries were compiled
using Matlab 7.0.2.

Some of the scripts are a little hard to understand. 

I'm not bothering to document this stuff properly because the binaries
are old versions of what we're using now, and I'd much rather you used
the newer ones on my website: www.ee.surrey.ac.uk/personal/n.dowson

Email me if you have problems. (See paper for email)
