Sorry, Mark, I haven't actually installed the library and tried this, I'm tossing ideas off the top of my head…

Hmm, if that line is a direct quote, then it may be a typo (you have an extra "e" in the middle). That might fix it, or perhaps:

Python.gray = gray
Python.scaleFactor = 1.1
Python.minNeighbors = 5
Python.minSize = [30,30]
Python.flags = cv2.cv.CV_HAAR_SCALE_IMAGE

void = Python.Run('faces = cv2.CascadeClassifier.detectMultiScale(gray,scaleFactor=scal eFactor, minNeighbors=minNeighbors,minSize=minSize, flags=flags)')

faces = Python.faces

Of course, to try it more simply for now, how about:

Python.gray = gray

void = Python.Run('faces = cv2.CascadeClassifier.detectMultiScale(gray,scaleFactor=1.1, minNeighbors=5, minSize=[30,30], flags=cv2.cv.CV_HAAR_SCALE_IMAGE)')

faces = Python.faces

Is that any better?

Cheers,
-Dick
