That piece of code tries to load the OpenCV 1.0 library. This might not work with newer versions of OpenCV.

tried the code from this
blog. In the second line it's given: "from CVtypes import cv". I even
downloaded CVtypes and pasted it in the same folder where the program
is. Even when I type "from CVtypes import cv" in interpreter mode, it's giving the same error. There is one thing about the "Wrappers" that I don't seem to follow. Here is the error: ">>> from CVtypes import cv Traceback (most recent call last): File "<stdin>", line 1, in <module> File "CVtypes.py", line 38, in <module> _cxDLL = cdll.LoadLibrary('libcxcore.so.1') File "/usr/lib/python2.7/ctypes/__init__.py", line 431, in LoadLibrary return self._dlltype(name) File "/usr/lib/python2.7/ctypes/__init__.py", line 353, in __init__ self._handle = _dlopen(self._name, mode) OSError: libcxcore.so.1: cannot open shared object file: No such file or directory" Can't make anything out of it even when I tried to...

Thank you so much. Since the formatting is lost, I created a gist for others to make it easy to copy. https://gist.github.com/126...

cv.DestroyWindow("camera") should solve the problem with exiting the program.

Nice! I've got some motion detection going on over here if you're interested: http://appdelegateinc.com/b...

Did you buy the book? I find the OpenCV documentation is very hard to follow.

"When you’re struggling with SWIG-generated Python bindings, or have some C library without bindings that you would like to use, give ctypes a try. "

This reminded me of this
"If you have a problem - if no one else can help - and if you can find
them - maybe you can hire: The A-Team."

I almost want somebody to geekerise the lyrics and make them about ctypes now.

Hey,
I found the solution already. Needed to put the
'haarcascade_frontalface_default.xml' file in the same directory as your little programm. When I runned the code, it seems to work fine. I only noticed that the program is often detecting my chin and mouth.. and not the whole face. Is this because I'm to close to my cam or is there a other solution for.

Thx,

Stefan

ps: I also needed to put "from opencv.highgui import *" above the code. Did yours work without?

Can you help me with this problem. I really don't know what to do.
