how to combine two different binary image?

Halo im Indra. i have a final project to combine two images from optik disk segmentation and optik cup segmentation on binary image. i cant combine both image. optik disk in white and optik cup in black

. and the result like this picture. can you help me?

Use bwperim(). From left to right for your 4 desired images:

image1 = bwperim(opticCup);
image2 = bwperim(opticDisc);
image3 = opticsCup & opticDisc;
image4 = bwperim(image3);
% or
image4 = image1 | image2;

sorry mr, i can't run that code. when i run that code something eror.can you give some altenative methode?

[Image Analyst]

Why not? What are your two binary images called? If they're not called opticCup and opticDisc, then use their actual names - whatever you called them.

What error do you get? You forgot to post it. Copy and paste all the red error test along with your code after you read this.

Post your two original binary images, I can't really use the image where you have both of them in the same image. Make it easy for me to help you, not hard.

I could have gotten to it tonight if you had posted your images and code, but now you'll have to wait until sometime tomorrow.

thresholdValue = 0.9;

BIOpticDisk = subImage > thresholdValue;

figure(1);

subplot(2, 6, 9);

imshow(BIOpticDisk);

title('Binary Thresholding');

thresholdValue = 250;

BIOpticCup = subImage2 < thresholdValue;

figure(2);

subplot(2, 6, 9);

imshow(BIOpticCup);

title('Binary Thresholding');

thats my code for binary image Optic Disk and Optic cup. for optic disk, im using HSV for detect optic disk and for optic cup im using Green Channel from RGB to detect optic cup. but when i combine both its something error. i dont have the result.

[Image Analyst]

I can't run this code because you did not post "subImage". And if that's just a portion of your entire image, post your entire image too.

[Indra Ginanjar A.T]

my subImage is thats picture which im posted. the subimage is the result from segmentation optic disk and optic cup. full image is retina picture like this.

[Image Analyst]

The top portion of your script is missing. Why don't you make it easy for us to help you? subImage is not an RGB image. Don't make me recreate the top part of your script. Just attach the full script m-file with the paper clip icon.

this my full script matlab. i wish you can help me ..

I know this is late, but somebody else might need this answer.

First you have to make sure to have the same size of both the images. Then, if the image is binary (only 0 and 1), you can use the 'or' function.

a simple example:

A = [1 0 0 0];

B = [0 0 0 1];

C = or(A, B) = [1 0 0 1]

I = imread ('Image1.tif');      % Getting the first black and white image.
J = imread ('Image2.tif');      % Getting the second black and white image.
I_bw = imbinarize (I ,0.9);     % Converts image to black and white image with limit value 0.9 (binary).
J_bw = imbinarize (J ,0.9);

K = or(I, J);                   % Combines the binary images.
imshow(K, []);                  % Displays the combined image.
