Hey,
In gridflow i remeber seeing this application:  http://createdigitalmotion.com/2007/01/18/open-source-motion-tracking-with-multiblob-for-gridflowpd/
How can i implement the same application in PD-extended without using gridflow? since it wont have access to #labeling.
I saw some patches like pix_multiblob_help.pd in pd-extended. Would it be similar to the one in the link??

thnks a lot
