Fuzzy logic Approach to Image Fusion

Hi,

I am trying to test fuzzy logic approach to fuse too images. Following is the source i'am using:

    function Y=fuse_fuzzy(M1,M2) 
%Y = fuse-fuzzy(M1, M2) image fusion with Fuzzy Logic method 
%  MI - input image #I 
%  M2 - input image #2 
% Y  -fused image 
% check inputs 
%Size of the two input images should be same 
[z1 s1 ]  = size(M1); 
[z2 s2] = size(M2); 
 if (zl ~=  z2)||( s1 ~=  s2) 
     error('lnput images are not of same size');
 end; 
%Color map 
M1=rgb2gray(M1);
m = gray(256); 
f=readfis('fuse.fis'); 
colormap(m); 
im=evalfis([M1(:) M2(:)],f);
% Converting the column into matrix 
k=l; 
for i=l:1:zl 
for j=1:1:s1 
img(j,i)=im(k); 
k=k+1; 
end;
end;
Y=img; 
%Computing entropy for input and fused images 
entropy(M1); 
entropy(M2); 
entropy(img) 
end

My problem is that i couldn't understand what 'fuse.fis' file is ? and how to create it if it not exists ?

Thanks a lot

Hi, in which version of matlab can i find the syntax: fuse_fuzzy(...) because my project M2 is on fusion of 2 descriptors for face recognition using fuzzy logic.

thanks

nana, the code for fuse_fuzzy() is given right there in the question. It's code the poster wrote or got from somewhere. I don't believe it's Mathworks-written code.

fuse.fis consists of input and output membership function

note: u can add fuzzy rules also

find the code below
