We are about to switch to a new forum software. Until then we have removed the registration on this forum.
I released a new version which got a bug fixed in the method findCentroids(). This method is called only and if the blob's centroid (getCentroidX, getCentroidY) is required, also it's not called internally. Thanks to Mauro Herrera for reporting the bug. =D>
Please note: I'm working on the issue opened by clankill3r on github, which it's not a bug, but a weakness of the type of labelling algorithm used (also using some image operator like blurring and dilatation before the blob detection, improves the result quite a bit).
INPORTANT The versions on code.google.com are old and should not be used anymore.
