Basicly you can stay with GEM, it can do the trick. If you insist to stay with WindowsXP you can use virtually every webcam as they all provide drivers for the monopol OS. Do a search on previous posts about recomendations as this is a regular FAQ. Essential advise is to prefer CCD instead of CMOS cams, which are more noisy.

That's interesting; i recently had a project (yesterday) where i tried to use pd, GEM and a Logitech Quickcam (Pro 4000) on a WinXP and pd crashed when i loaded a pd patch using GEM objects. after uninstalling the Logitech software pd ran nicely again - but i could not use the cam. weired.

I recently did a project in WinXP with a webcam, PD, and GEM and it worked beutifully. I was able to have 9 concurrently running captures and 3D without a decent framerate. I think there are some GEM picture analysis objects, but I'm not familiar with them. PDP+PiDiP on Linux is the best way to do this, but WinXP and GEM, perhaps with an OSC connection to something like Eyesweb will work. I used a Logitech Quickcam.

hi vasily

i did this kind of things (colordetection) with pd and pdp+pidip. it works like a charm and it's fast, even if you use an object multiple times, in my case 17. it's linux and macOSX only. but i think you should give dynebolic (dynebolic.org) a try, it's a linux live-cd and i think the mentioned software should run without installing anything. http://ydegoyon.free.fr/pidip.html

if there is no 3D involved i think you rather take this then using gem. most people i know working with linux and webcams are using the ones from philips. i think 740 (yellow rubber focus, not red) but i tried logitech and it worked as well, have a look on the supported models list of the pwc-driver: http://www.smcc.demon.nl/webcam/

if you need to stay on win i don't have much idea what to use, probably eyesweb could do this kind of things. (OSC communication with pd)

Hi list, My friend is doing a project where he will need to process the image from a webcam in realtime, to detect changes in the color of certain areas within it's view. I thought PD/GEM might be a good tool for this. Has anyone had any experience, working with webcams from PD? Which webcams are the easiest to connect to PD? What other externals/packages will I need? Thank you in advance, Best regards, Vasily mailto: kvas at naumen dot ru

P.S. BTW, the OS used will most likely be WinXP
