Call regionprops(binaryImage, 'Centroid')
binaryImage = bwareafilt(binaryImage, 1); % Take largest only.
props = regionprops(binaryImage, 'Centroid') % Find centroid.
xCentroid = props.Centroid(1);
yCentroid = props.Centroid(2);
See the Image Segmentation Tutorial in my file Exchange for a full demo:

Just crop out each blob one at a time and compute the central moments one at a time.
