3D image from 10rgb slices

Hi I have 10 rgb images (100x 100x 3) and want to combine them into a single 3D image. Is it possible ? thanks in advance Sermed

So which of the two methods below is what you want?

Answer 1

[Image Analyst]

How do you want to combine them? Do you want a single x00x100x3 image that is the average of all of them? If so, cast them to double and add them, then cast back to uint8 (if that's how they started).

aveImage = uint8((double(image1) + double(image2) + ... + double(image10))/10);

Answer 2

Because RGB is already 3D, you can combine them in the fourth dimension

I1 = ones(10, 10, 3); 
I2 = 2*ones(10, 10, 3);
All(:,:,:,1) = I1;
All(:,:,:,2) = I2;

or you can stack them one after the other in the third dimension:

All(:,:,1:3) = I1;
All(:,:,4:6) = I2;

or you can use cells

All{1} = I1;
All{2} = I2;

Answer 3

Hi, here is an other viewpoint that combines the two given answers : you create an Image_Stack and then do what you prefer like median, mean ... :

Stack=zeros(100,100,3,10);

% ur first image I1

Stack(:,:,:,1)=im2double(I1);

%..and so on until 10

Stack(:,:,:,10)=im2double(I10);

Sum=zeros(100,100,3);

for iter=1:10

Sum=Sum+Stack(:,:,:,iter);

end Combined=Sum/10;

I hope that helps .
