The easiest way I can think of is to append the entries from multiple images into a single table in a loop and then write that table to an excel or csv file. The following code illustrates this idea:
I{1} = imread('coins.png');
I{2} = imread('cameraman.tif');
final =table;
for id=1:2
data=regionprops('table',I{id}, 'Area', 'EquivDiameter', 'Centroid', 'MajorAxisLength','MinorAxisLength')
final = [final;data];
end
writetable(final,'mydata.csv')
