Argghh, I didn't try the objects and they freeze (or sometime crash) my PD. The objects draw perfectly under PD but i got this error : error: [pix_opencv_contours_convexity]: cannot handle this format
(1234567) ! or [pix_opencv_haarcascade]: ERROR: Could not load classifier cascade Why ? Any idea ?
yes, the classifier cascade files are the XML's files you have in the
pix_opencv folder, the default ones is haarcascade_frontalface_alt.xml
and it must be in the same folder where you have your "pd_linux" or
"pd_darwin" files.
also the object [pix_opencv_haarcascade] has a message |load $1( to
load any xml file trained as classifier cascades. The default one I'm
using is trained to detect human faces but you can train one to detect
any object you want (it's not easy at all but it's possible).
you can download other "OpenSourced" haarcascades (fer example) here:
here:http://alereimondo.no-ip.org/OpenCV/34
and here you have some info on how to train one: http://note.sonots.com/SciSoftware/haartraining.html
salut, ll.

OK, now it works on PowerPC, MacOSX.4.11
Here the method :
? Download this three libraries with Fink : libjpeg + libpng3 + libtiff
? In Terminal : cvs
-d:pserver:anonymous@opencvlibrary.cvs.sourceforge.net:/cvsroot/
opencvlibrary login ----> then hit 'enter' on your keyboard cvs -z3 -d:pserver:anonymous@opencvlibrary.cvs.sourceforge.net:/
cvsroot/opencvlibrary co -P opencv ----> download opencv sources? with a text editor, open the file : cvcap_qt.cpp look for '__BEGIN__' and change it by '__BEGIN__{' look for '__END__' and change it by '}__END__' ----> save
? In Terminal ----> go to your opencv folder you just download and create a new
folder 'build' : cd blabla/opencv mkdir build cd build ../configure CPPFLAGS="-I/sw/include" LDFLAGS="-L/sw/lib" make sudo make install ----> enter your password? With you browser go to : http://hangar.org/wikis/lab/doku.php?id=start:puredata_opencv ----> download pix_opencv-0.1a.tar.gz and decompress all : http://hangar.org/wikis/lab/pd/pix_opencv-0.1a.tar.gz ----> download PD-extended sources and decompress all : http://downloads.sourceforge.net/pure-data/Pd-0.39.3-extended.tar.bz2 ----> download the makefile for macosx : http://hangar.org/wikis/lab/pd/opencv/Makefile.darwin
? In the Finder : ----> change 'Makefile.darwin' by 'Makefile' and then overwrite
the 'Makefile' in 'pix_opencv' folder you just download? With a text editor : ----> open this new 'Makefile' and change : PD_DIR = /*/Pd-0.39.3-extended/pd (enter the path of the 'pd'
folder in 'Pd-0.39.3-extended' folder you just download from
sourceforge) GEM_DIR = /*/Pd-0.39.3-extended/Gem (enter the path of the 'Gem'
folder in 'Pd-0.39.3-extended' folder you just download from
sourceforge) ----> save? In Terminal : ----> go to the folder 'pix_opencv' with 'cd ' export MACOSX_DEPLOYMENT_TARGET=10.4 make clean make
? Then copy the '.pd_darwin' create in the 'pix_opencv' folder in
your '/Applications/Pd-0.40.3-extended-20080315.app/Contents/
Resources/extra/Gem/' for exempleHope it will help and hope i have not made mistake. Thx to Lluis for his help. ++

However, when I try to load any of them PD gives me this error::

I got this error too, but only when gem was not loaded. when gem is loaded, everything is fine.
In order to make the opencv objects work I always had to set colorspace RGB. otherwise, I did no see any effect. I think the default on osx is yuv. anyway, will test a little more. great stuff! marius.
