pyOpenCV demo (face detection with Python)

When I first played with openCV I had no idea how good the facial detection would be, or how fast it might run on my MacBook. I’m recording this demo so you’ll know what to expect…

pyOpenCV is the Python binding to the open source openCV (originally created by Intel for vision research). It comes as a Windows exe, it builds on Linux just fine, I posted some Mac openCV build notes a few days back. is the demo program for facial detection. The goal of the video below is to show you that:

  • is pretty good at facial detection on a standard laptop
  • light sources really degrade the performance


The openCV book is rather excellent, everything is in C++ but the Python API is easy to figure out and the reference text makes it all clear.
