OpenCV Eigenfaces

Example use of facial recognition using OpenCV's eigenface implementation.

Usage

./test_eigenfaces.py

N.B requires a csv file at

./faces.csv

##Dependencies OpenCV

brew install opencv

Create your virtualenv allowing for site packages, so you can access opencv python bindings

virtualenv --system-site-packages

Then install deps from requirements.txt

pip install -r requirements.txt

Preparation

I used the set of example face images available from AT&T Labs Database of Faces.

wget http://www.cl.cam.ac.uk/Research/DTG/attarchive/pub/data/att_faces.tar.Z \
&& uncompress att_faces.tar.Z \
&& tar xvf att_faces.tar

Create the necessary csv file

./create_csv.py orl_faces > faces.csv

This will create a csv in the form file;label. See OpenCV Docs for more info.

This is just a python implementation of some of the behaviour shown in the OpenCV docs.
