ola,
the package that is on the official page is for Pd-extended 0.41-4
( as it is written on this page ), this doesn't matter for pdp_opencv,
but it matters for pix_opencv ( it is for gem 0.91 ).
use pdp_opencv and pdp2gem is you really need gem,
but for analysis you might no need it at all
Hello list,
I wonder if there are any tutorials available on how to use OpenCV
with Pd? I'm trying to download necessary components using the

The reason I want to build it into an external is for convenience and for the

Is this the receiving function? I would write it more like:

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
. I appreciate all
input.
Thanks to all,

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.

That looks like a c++ error to me, maybe you should be compiling it
I think I figured it out. It looks like I have to use t_symbol *sym

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

it. I will also continue to figure out the external because I think
I see you have the ability to capture from an avi built in already:

else pCap = cvCaptureFromCAM( 0 )
This is code looks great. I could figure it out from the code but if

I haven't looked at this yet, and have no external coding experience.
However, I'm wondering if it would be an easier task to port this
library to mimic the pix_* objects in Gem? Maybe you could look at the
Gem source and figure out how to do this. Or better yet, compare the
code you have here

BTW the algorithms for pix_multiblob are way, way over my head(seriously)!
