I have been working on a open source face recognition demo tool called FaceL for the past few months.   FaceL is a simple and fun face processing and labeling tool that labels faces in a live video from an iSight camera or webcam.  It uses OpenCV for face detection, ASEF correlation filters for eye localization, and a Support Vector Machine for face classification.    FaceL is implemented in python (using PyVision, wxPython, SciPy, OpenCV, libsvm, and PIL libraries) with a binary executable available on Mac OS 10.5 Intel.  (Windows and Linux versions expected soon.)  

FaceL has been fun to work on and I thought that the NumPy community might like to see their software in action.

FaceL source code, videos, and executable can be found at:
