basic patching with Gem
Go to the PureData Help menu, there you have the basic examples we have seen today ::
Help -> Browser -> examples -> Gem -> 01.basic -> 01.redSquare.pd
Help -> Browser -> examples -> Gem -> 04.pix -> 05.film.pd
Help -> Browser -> examples -> Gem -> 04.video -> 00.SimpleVideo?.pd

setting up your system
-Ubuntu Linux Easy Way :
Download and install pd-extended ubuntu package here http://puredata.info/downloads Download and install pd_opencv bindings here http://artefacte.org/pdpkg/
-MacOSX? Easy Way :
Download and install pd-extended MACOSX package here http://puredata.info/downloads Download the binary objects of pd_opencv for MACOSX. Unpackit and follow the instructions in the README file.
Device of supported USB cameras in Linux http://www.linux-usb.org/devices.html Look in the "Multimedia" devices section, the easy is to find a device with a driver which allready is in the main kernel source, but also the others will work.
Any DV1394 device (dv cameras and/or Analog/Digital Converters) works well on Linux
The IEEE1394 Digital Camera List http://damien.douxchamps.net/ieee1394/cameras/search/ Those are uncompresed video cameras, (actually not supported in thr linux PD version)
Computer Vision Test Videos
here http://muonics.net/cvMovies/ you have some test videos that relate to computer vision.
Made a tour for all the help examples, one by one, test them in diferent contexts and try to adjust the parameters as you need
Simple practical example
Download Physical modeling examples here http://artefacte.org/BALTAN_Workshop/pmpd_example.tgz
Repository of Haar's Cascade XML files http://alereimondo.no-ip.org/OpenCV/34 here you have a package with more haarcascade clasifiers http://artefacte.org/BALTAN_Workshop/haarcascades.tgz

The fruit detector works....
People are working on their projects, comparing different solutions, pd is an easy tool to use for prototyping applications...
Fixing some problems with cameras encountered during the workshop : an experimental driver for DC1394 cameras has been added to PiDiP, only working in black&white for now
Adding the examples seen in this workshop to the software packages and fixing a few bugs to make a new software release : pd_opencv-0.2-rc4
