Hi Eliska, you can try this code:

% Load image
I = imread('your_image.bmp');
% Define conversion factor
conversion_factor = 0.14; % mm/pixel
% Get size of image
[M, N] = size(I);
% Create spatial referencing object
ref = imref2d([M N],conversion_factor,conversion_factor);
% Plot points on millimeter-scale axis
imshow(I, ref);

I was trying to use imred2D function, but as you can see I have a problem here. I don't know what to do with a table
