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.
