Hi, I have 20 images of a ball in different positions in an interval of 1 minute. i would like to calculate its velocities between each interval and plot its pathway in graph. I was thinking of obtaining its centroid and deducting it from the later centroid position. but the problem i'm facing is doing it in loops.the centroid position only holds 1 value so i cant deduct it from the later.

So you really cannot have an array of positions? I am sure that MATLAB supports arrays. So now just store all 20 centroids in one 20x2 array.

Position = zeros(20, 2);
for iImage = 1:20
Value = determine_the_position_for_image(Image{iMage});
Position(iImage, :) = Value;
end
