Note: The above will reduce frame rate to 8fps and scale the image down to something more sensible.
Interestingly. On various media files it tends to have a lot of false positives. I assume "neighbors" is somewhat like a threshold value. So I defaulted this to 75 in the gstreamer element. I also see plenty of misses. Though I do like the performance.
It may be worth pointing out that with additional functionality like this. You can play other face detection methods off against each other for building more complex and less biased data sets for training.
This adds a gstreamer wrapper which will opens the facedetection to run on all types of media rather than just jpeg images.
Example for playing any video file
After installing most of gstreamer.
export LD_LIBRARY_PATH=
pwdexport GST_PLUGIN_PATH=pwdmake && GST_DEBUG=3 gst-launch-1.0 filesrc location=somefile.mp4 ! decodebin \ ! videorate ! video/x-raw, framerate=8/1 \ ! videoscale ! video/x-raw, width=640, height=480 \ ! videoconvert ! identity sync=true \ ! queue max-size-buffers=3 leaky=1 \ ! libfacedetect ! videoconvert ! xvimagesink sync=false

So this may help you improve things more!
