Re: [PD] advices needed to track dancer (kinect, osceleton, tuio, pidip)
hello, Thank's for your replies. if you work with kinect, osceleton send also the coordinate of the user before it track it with the psi pose. you can just listen to /user/1 /user/2 etc ... to get the coordinates (3 floats) It's good to know! Thank's for that. I think i am gonna follow this option with osceleton as it seems to be the most simple. I should look more closely to the pdp_opencv though but i realised that the pdp_freenect requires a lot of cpu (40%_50%) on my thinkpad w500, and combined with the pdp_opencv objects it is not really usable so far. And i have got also a segmentation fault sometimes that makes pd crash. (Pd 0.43.1test2). I should maybe go back to a previous version.. delphine On Tue, Jun 21, 2011 at 5:38 PM, olm-e o...@ogeem.be wrote: hi, i need to track a dancer to project and map videos on him (one of the video is a human body on a black background).

Perhaps look at the pix_/pdp opencv libraries, they might help you more pp On 6/21/11 10:28 AM, manecante maneca...@googlemail.com wrote: hi, i need to track a dancer to project and map videos on him (one of the video is a human body on a black background).
