Mission statement:
^
The "raison d'etre" of this DEMO is to demonstrate the power and
applicability of wavelet methods, by means of a simple and lucid
example code. It certainly NOT represents the state of the art in
image fusion.
Scope: Two similar images are fused into one image that is better
than each of the originals.
Method: See [LMM], which is the proper reference to the method.
In fusion.m the method is described as well.
Means: MATLAB, the Image Processing Toolbox and the Wavelet Toolbox.

Where: One can download the DEMO from either [OTZZ] or directly from [Z],
see the References below.
You may either: (A) download DEMO.tar.Z.uu (approx. 0.7 Mb)
or: (B) download all files other than DEMO.tar.Z.uu
Let (A) be followed by:
uudecode DEMO.tar.Z.uu
zcat DEMO.tar.Z | tar xvf -
All the following files should be retrieved:
README
fusion.m ave.m atb.m ave.m fillC.m
hoed_A.tif hoed_A.tif.mime
hoed_B.tif hoed_B.tif.mime
office_A.tif office_A.tif.mime
office_B.tif office_B.tif.mime
Here hoed_A.tif.mime is just the "base64" mimencoded version
of hoed_A.tif, etc. This is useful if you encounter difficulty
in downloading tif-files straight away.
How: All that you have got to do now is to enter MATLAB and type: fusion
If you want to understand what happens then read the comments in fusion.m
You can choose a different wavelet from the toolbox easily.
You can insert your own pairs of images easily.
And... you can try to improve the algorithm further.
Good luck!
