Hello, I want write this formula but all result is zero :(
input = imread('cameraman.tif');
[m , n] = size(input);
L = 255;
Xmax = L - 1 ;
Xc = 0.5;
Fe = 2;
Fd = 30;
Pmn = ones(m,n);
Pmn = double(Pmn);
for i = 1:m
for j = 1:n
Xmn = input(i,j);
Pmn(i,j)=1/((1+((Xmax-Xmn)/Fd)).^Fe);
end
end

Use
Xmn = double(input(i,j))
