MATLAB: How to store images of different dimension in a single array

arraysimages

Hello everyone!! I am stuck with a serious problem here. I need to store images each of different dimension in a same array. How can i do that?? The size of each image keeps changing. I cannot store the images individually because it runs in a loop and images are huge in number. please suggest me a solution or any other alternative method.

Thanks in advance!!

Create a cell array instead, each cell can contain a image of different size:

N = number_of_images;
my_im_cell = cell(N,1);
my_im_cell{k} = image(k); % where k is the image index/number

Hi,

what you like to do can be done with eval:

n = 5;
for k = 1:1:n;
      eval(['array_',num2str(k),'= k^2+2*k;']); % Just an example
end

But I would recommend avoid eval and use a Cell instead to capture the output:

n = 5;
array = cell(n,1);
for k = 1:1:n;
      array{k} = k^2+2*k;
end
