Yeah, I took the openCV blobtrack code from the examples and modified it
just slightly. I didn't document all the changes, because it was never
meant to last for more than one project. I simply added the pd netsend
stuff, added a few sliders to control parameters, added an automatic
background model refresher, and blacked out some areas of the image that
I didn't want processed.
Attached is the patch that I use to receive the blob data in Pd (also
with some customizations).

Sorry forgot to ask. Do you have a pd abstraction for this? If not I
will see what I can cook up. I think iemmatrix might do the trick.

I see you have the ability to capture from an avi built in already:
avi_name = argv[i];
if (avi_name) pCap = cvCaptureFromFile(avi_name);
else pCap = cvCaptureFromCAM( 0 )
This is code looks great. I could figure it out from the code but if
you have any use instructions let me know. It would be great to get a
gui for this thing. I will try to figure that out.
Thank you,

Thanks Mike,
Its awsome how helpful people in this community can be. I will check
out you code and modify it if need be, like add the option to use an
avi in order to be able to calibrate things and such and I will post
it. I will also continue to figure out the external because I think
that would be a neater approach and cause I dont accept defeat very
easily.

Hi Alain,
I've used the OpenCV blobtracker with Pd before, and I simply send
blob positions and sizes over UDP using u_pdsend.c
I've attached my code and makefile... look in blobtrack.c and
search for where I use the pdsend_init() and pdsend_message()
functions... it's pretty simple.
Then you just use [netreceive] in Pd and parse the list as you deem
necessary.
Hope this helps,
-Mike
P.S. my blobtracker code is meant for use with a live camera, not
with .avi files.
