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. > ++ > > Jack > > > Le 30 avr. 08 à 19:57, Jack a écrit : > >> OK, now it works on PowerPC, MacOSX.4.11 >> >> Here the method : >> >> ?
