Blob id in contour OpenCV

Hello all !
I would like if there was some implementation of blob id when using opencv contour, perimeter, …
I know there are this feature in freeframe plugins, but opencv is much more efficient !! (many thanks to all contributor !!)

shall we re-compile opencv to make this feature in vvvv ? or would it be possible to deal with blob id in the patch ?

thanks in advance !

the Tracker can find those ids (and additionally stabilize them)

wow !!!
I didn’t know about this… many thanks !!!
