separate information out of cv.jit patches

I've been having a problem while using cv.jit patches.
Im pretty much a rookie in max and have not yet figured out ways to separate the multiple blob (in this case). I've used a jit.iter to extract the coordinates, but when there are multiple blobs it only output the last one. I want to have the coordinates of the different blobs.
The patch is included beneath.

I realise I might be missing some very basic insight into extracting output from a matrix. If somebody is willing to refer me to some tutorial for this or povide me with an example patch they would make me very happy. Till then I will be happy with an answer to the jit.iter problem.

thanks,
Rik
