Unless you expect the count to be something other than 12, you can use bwlabel()

Yes, that is a labeled image in MATLAB terms. Each different area has been given a different number, and each different number has been represented as a different color based upon the current colormap() .
Perhaps what you wanted was some text written onto each blob. If so then use regionprops() to request the Centroid . Loop through the returned information, pull out the Centroid information, and text() the appropriate label number at that location.
