2D images into a 3D stack of images

Hello All,

I have lot of 2D images and would like to stack them in a 3D volumetric cube and then plot it. I have written a code which is making a 3D array of it but I am not getting a correct plot of all the stack as a 3D cube. My code is given below, please suggest the modification or idea by which I can plot the 3D cube as a stack of all the 2D images.

for i=100:259
    % {} = cell array
  images{i} = imread(sprintf('%d.png',i));
  I{i} = (images{i});
end

myImage = cat(3,I{100:258});
image=myImage(:,:,1);
imagesc(image);

vector=reshape(image',numel(image),1);
X=ifft(image);

Although eventually the end result would need me to produce the inverse FFT of that stack. But, first concern is to produce the stack.

image is a built-in function so do not try to use it as the name of one of your variables.

I have no idea what it means to "plot" a volumetric image. I only think of "visualizing" volumetric images and in that case we use Avizo: https://www.fei.com/software/avizo-3d/ because MATLAB does not have powerful 3-d visualizing capabilities - it has only simple iso surfaces and cut-away views.

For a "plot", I'm thinking of a graph or something you'd plot with the plot() function. Please explain what exactly is to be plotted from your volumetric image. Show a screenshot if you can.

First, thanks a lot Image Analyst. I read many of your posts and I am truly very admired by your knowledge and experience as I saw on your profile. So, thanks a lot for your reply.

Second, I am a baby in Matlab as I just started for a little project of mine. I will not use image as a name of variable now.

Actually, what I am trying to do is because I am working in Optical coherence tomography (OCT) I have a lot of 2D images which I want to stack on top of each other and then see as cube or volume of all those images as a stack and then see and call out which ever slice I would like to call from that stack. As you must have seen that I was able to create a 3D variable but when I did ifft and plot it then all I could see was a image as seen it in the screenshot but to see the 3D cube I tried to rotate this image by the 3D rotate option in the figure palette but it's just one image instead of the whole stack.

So, my problem is that may be I am plotting one image but not the whole stack which I can rotate and see and then perform FFt on it.

Please be patient if I am not clear with my statements as I am very new to MATLAB but I am open to questions and suggestions.

I didn't see anything in your code that would display anything. What code did you use to display that axes?

By any chance could you figure it out?

I am working in something similar but I got 1,500 pictures.
