I got the following code from net
% getting the size of the input image
im_final=floor(double(image)/(2^output_bits));
[im_final_x im_final_y]=size(im_final);
% setting the size of the co-occurence matrices depending on the grey level depth
CO_size=2^input_bits/(2^output_bits);
SGLD=zeros(CO_size,CO_size);
switch theta
case {0}
for i=1:im_final_x
for j=1:(im_final_y-d)
SGLD(im_final(i,j)+1,im_final(i,j+d)+1)=SGLD(im_final(i,j)+1,im_final(i,j+d)+1)+1;
end
end
% make the SGLD matrix symmetric by adding it's transpose to it
SGLD=SGLD+SGLD';
% normalize the SGLD matrix to values between 0 and 1
SGLD=SGLD/sum(sum(SGLD));
But what is the logic of this program,ie how it actually works?
