Saving the image names and bounding box coordinates in different file formats

I've written a Matlab code to crop an image with respect to a mask.

function Crop_Img = Crop_Xray(Img,Mask)
% Find borders
vertical_profile = sum(Mask,2);
horizontal_profile = sum(Mask);

indexes = find(vertical_profile >0);
upper = indexes(1);
lower = indexes(end);

indexes = find(horizontal_profile > 0);
left = indexes(1);
right = indexes(end);

% Crop Img
Crop_Img = Img(upper:lower, left:right);

end

I would like to save the individual image file names (*.png) and their respective bounding box coordinates (upper:lower, left:right) to a .csv, .txt, and .mat file. How should I do that?

Try this:

save('Crop_Img.mat', 'upper', 'lower', 'left', 'right');
imwrite(Crop_Img, 'Crop_Img.png');

Change the filename if you want.

My requirement is to save the image name and the respective bounding box coordinates in adjacent columns.

So make a table with the table() function and save that. Look up the table() function in the help for sample code.
