I forgot to mention that I tried jit.scissors as well but that does not seem to work correctly either...

still gives me all of the data from the first outlet...

Subject: Re: [jitter] cv.jit.label - cv.jit.blobs.centroids for multiple objects

sorry to be thick headed about this but how to best then chop up the data fro cv.jit.centroids into several one cell matrix(s) (matrixi) (( :? ))

well - just zero values - if I use dim 4 1 for example, with 3 tracked objects then I get 3 cells showing up in my jit cell block - but they are all a 0.0 value

you said that centroids iterates through but I am not seeing this if i print the data -

(or i am not properly understanding this somehow) 

129.953 121.553 190.000, 161.600 158.482 85.000, 165.500 163.000 2.000

126.138 150.408 152.000, 160.090 182.321 78.000, 165.000 185.875 8.000

can someone give me a direction to fumble in please

> tracking for one as follows - how to do this with 3....

tracking is the same for multiple blobs too.

cv.jit.blobs outputs a single-row, 3-plane char matrix where the 

number of cells is the same as the number of labeled components. The 

If you open cv.jit.blobs.centroids.draw patch, you'll see that 

jit.iter iterates through all the cells in the matrix(all blobs) 

giving you a list of maxland values(x , y, area).

sorry to be thick headed about this but how to best then chop up the data fro cv.jit.centroids into several one cell matrix(s)  (matrixi) ((   :? ))

I tried to use 
jit.submatrix @dim 1 1 @offset 0 0
and
jit.submatrix @dim 1 1 @offset 1 0

you said that centroids iterates through but I am not seeing this if i print the data -
(or i am not properly understanding this somehow) 
here are 2 example bangs 

 129.953 121.553 190.000, 161.600 158.482 85.000, 165.500 163.000 2.000

hmmm - 
can someone give me a direction to fumble in please

cv.jit.blobs outputs a single-row, 3-plane char matrix where the  
number of cells is the same as the number of labeled components. The  
contents of each plane is as follows:
Plane 1: x-coordinate
Plane 2: y-coordinate
Plane 3: area

If you open cv.jit.blobs.centroids.draw patch, you'll see that  
jit.iter iterates through all the cells in the matrix(all blobs)  
giving you a list of maxland values(x , y, area).
