superimpose two images

[vidpai91]

HEllo sir,
I am newbie to image processing,I work on retinal image analysis. I use gabor filter to perform some operation on my image. I used gabor filter for 12 different orientations of an retinal image and i got 12 different output. now i want to superimpose these images on my original image(first visualized image with original image,second visualized image with original image...till the 12th imgage) and to display all the 12 images.How do i do it?

here is my code

Code: Select all

            I = getimage();
           I=I(:,:,2);
            lambda  = 8;
            theta   = 0;
           psi     = [0 pi/2];
            gamma   = 0.5;
            bw      = 1;
         N       = 12;
        img_in = im2double(I);
%img_in(:,:,2:3) = [];   % discard redundant channels, it's gray anyway
img_out = zeros(size(img_in,1), size(img_in,2), N);
imshow(img_in);
title('input image');

for n=1:N
    gb = gabor_fn(bw,gamma,psi(1),lambda,theta)...
                        + 1i * gabor_fn(bw,gamma,psi(2),lambda,theta);
   
       img_out(:,:,n) = imfilter(img_in, gb, 'symmetric');
    imshow(img_out(:,:,n));      //gives me 12 different visualization output
       theta = 15 * n;  % next orientation

 end

this is my original image

and this is the output which i got using gabor filter

There are many different ways of placing one image on top of another, depending on what you are trying to show. Perhaps you can put up the original and a couple of your outputs, and describe what you want.

You can put them somewhere like dropbox.com and paste the links here.
