multi channel Image reconstruction

How can I reconstruct an image from [3410, 33, 33, 8] sub-images?.

You have to arrange the matrices into mXnX3 ..to make a image. Have a look on reshape but you need to be confident on order of the arrangement.

How were the parts arranged relative to each other?

Do you currently have an numeric matrix, or do you have cell arrays?

Here it is a pansharpening project where two images (single channel image, 8 channel image) are merged to make a new image (8 channel). I crop sub-images from both images ( 1 channel and 8 channel ) and tiled it to feed CNN for training. It is an image restoration problem (regression problem). After training, I tested it and model gave desired 8 channel sub-images [3410, 33, 33, 8]. Now I have to reconstruct an image from sub-images.

This is how I extract sub-images(Code)

load('D:\keras-program\practice\MS_data.mat') %load image
image=M;
g=size(image,3);

%%settings sub-image dimension according to requirement

size_input = 33;
size_label = 21;
scale = 4;
stride = 14;

%%initialization

data = zeros(size_input, size_input, 1, 1);
label = zeros(size_label, size_label, 1, 1);
padding = abs(size_input - size_label)/2;
count = 0;

%%generate data

im_label = modcrop(image, scale);

%%%%%%%%%%%%%%%%%%
function imgs = modcrop(imgs, modulo)
if size(imgs,3)==1
    sz = size(imgs);
    sz = sz - mod(sz, modulo);
    imgs = imgs(1:sz(1), 1:sz(2));
else
    tmpsz = size(imgs);
    sz = tmpsz(1:2);
    sz = sz - mod(sz, modulo);
    imgs = imgs(1:sz(1), 1:sz(2),:);
end
%%%%%%%%%%%%%%%%%%%%%%%%%

[hei,wid] = size(im_label);
im_input = imresize(imresize(im_label,1/scale,'bicubic'),[hei,wid],'bicubic');

for x = 1 : stride : hei-size_input+1
   for y = 1 :stride : wid-size_input+1
       count=count+1;
       for i = 1:1:g     
            subim_input = im_input(x : x+size_input-1, y : y+size_input-1, i);
            subim_label = im_label(x+padding : x+padding+size_label-1, y+padding : y+padding+size_label-1);

              data(:, :, i, count) = subim_input;
              label(:, :, i, count) = subim_label;
          end
      end
  end

order = randperm(count);
data = data(:, :, :, order);
label = label(:, :, :, order); 
save('MS_reduce.mat', 'data', '-v7.3')

Now I am stuck to reconstruct an image. Any reference code or suggestion as I am new in this area.

Thanks
