hi pd friends, im working on an installation and i need to analize a public space with a web cam and track the movement of the people in the space... i would like that the pd can give me back the coordinates of the people ...is this possible with pd? is there something like a multiblob object? which object or libraries do i need?
any idea would be appreciate
Yo,
I just did something really similar to this using ARToolKit. http://artoolkit.sf.net/
It detects the spatial orientation of markers, but the idea is similar. Maybe you could get people to pick up markers?
I have written some code (arudp.c) which sends the marker positions and orientations out as udp packets which you could read into PD via netreceive. Bit snowed under at the moment, but let me know if you want the code.
Best regards,
Chris.

hi chris,
i was about to include liblo (http://plugin.org.uk/liblo/) to artoolkit. since i'm really new to programmation i would like to see your code as an example! do you use vloopback to have v4l in gem and in artoolkit?

The code is currently on a PC in the installation space which I forgot to back up in the mad rush to get it working, so I'll have to nip in there later today and put it on a USB drive. I'll put it up on http://mccormick.cx/code/argraf/ at some point later today.
I have not used vloopback. Will check it out - sounds exciting.

Yep, my server has been bouncy lately so I did a real time re-install last night which had some pretty strange effects. All back to normal now. Thanks for the heads up.
Best,
Chris.
