Its good that you got it working though. There is some pretty amazing stuff in OpenCV.
In your code you are waiting just 10 ms for a key, and only after the image was processed.
So, if you wait a little bit longer(maybe 100ms, but this will slow down a lot the fps) you will be able to catch the keys.
However, there is also another problem cvWaitKey returns -1 when no key was pressed, but return a string(char) holding the key pressed, so you need to do the following:
if k!=-1 and ord(k) == 0x1b: # ESC
print 'ESC pressed. Exiting ...'
break
We managed to get up to 4 faces recognized at the same time.

Any help regarding this will be great!
I will probably release a first version of the code in the following weeks, so stay tuned!
I'm from Asia. I'm just starting to learn openCV.
Is there any opinion or advise from Sir as an expert to me to start learning opencv
Thank you very much.
Have a look at Gary Bishop's blog post, where he grabs a bitmap from the camera and displays this in a Wx window: http://wwwx.cs.unc.edu/~gb/wp/blog/2007/02/04/p...
Your if script silently hangs on this line for me:
cascade = cv.LoadHaarClassifierCascade('haarcascade_frontalface_alt.xml', cv.Size(1,1))
What can be the problem here? This xml exists in same directory and the is no any error output.
Thanks in advance!
i have an integrated camera on my laptop, which works with some apps like cheese.
while running this code, the camera(led) turns on, but nothing comes on the screen.
the script hangs and i have to ctrl+C to close it.
any pointers to help me with this situation will be appreciated.
thanks
