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
