Martin,
Thanks for all your help. I have a final question about the sprintf solution.
I have managed to get the
out going(I think) but I am not quite undestanding the atol()inlet part. I
have this.
void window_getframe(t_window *x, t_symbol *sym)
{
char* decode;
char

{
char* decode;
char symstr;
x-sym-s_name = decode;
symstr = atol(decode);
frame = symstr;
}
Is this the receiving function? I would write it more like:
void window_getframe(t_window *x, t_symbol
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
Thanks for helping. Well I basically have a rough sketch of all the objects
but I am having a tough
time with the outlet system. In a nutshell opencv uses an image structure
called typedef struct
_IplImage. Acording to them The structure IplImage came from Intel Image
Processing Library

Hi Alain,
wouldn't it be a lot easier to take the system that you already have and
use OSC or FIDO to send the values (that you were printing) to PD
for further processing?
I am greatly in favour of using different systems for different jobs
and letting
a protocol like OSC or fido (netsend)

You can only work with atoms in pd's message
thats all about. I have seen this used before with no
problems.

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

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
instead of t_symbol sym and the outlet has to be x-outlet_new(x-
x_outlet0, *sym). That seemed to work. The weird problem I am
having now it I get an error with the return(void *)x; I get error:

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
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
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 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)!
