Hellou. Could I ask for help finding the center of gravity of the object?

I have a white object on a black background, so a binary image. The object is irregular and similar to a flattened cylinder. How can we find its center of gravity please?

In the case where there are no disconnected pixels, then

info = regionprops( logical(YourImage), 'Centroid');
center_of_gravity = info.Centroid;

In the case where there might be disconnected pixels, then

info = regionprops( 0 + logical(YourImage), 'Centroid');
center_of_gravity = info.Centroid;

the "0 +" is there to turn the image into a label matrix instead of a binary image. If you pass in a binary matrix then normally the centroid of each disconnected region would be calculated.
