finding centers

Kirmse Robert
Dear Group,

i have a question regarding binary images.

I have thresholded an images and got many black blobs (thats what i want)
representing the locaions of particles.

Can anyone tell me the best practice to get the centers of these blobs.
Erosion would lead to the complete deletion of smaller blobs.
Something like skeletonize whould be fine which stops when one pixel is
left.
But skeletonize produces small lines out of lager circle-like structures.


Any hints or advices.


Regards
