Halo i want to combine 2d slices oct skin images into 3d, after that i want to make an automatic detection volume of epidermis and stratum corneum

i already combine like this

% Initialize variables

rows = []; columns = [];

% Loop through each slice

for k = 1:100

fileName = sprintf('_%d.txt', k);

% Read the text file

sliceImage = dlmread(fileName);

% Check the size of the first slice to initialize the 3D array

if isempty(rows) || isempty(columns)

[rows, columns] = size(sliceImage);

image3d = zeros(rows, columns, 8, 'uint8'); % Initialize 3D array

end

% Convert to uint8

sliceImage = uint8(sliceImage);

% Put this slice into plane k of the 3D image

image3d(:, :, k) = sliceImage;

end
