Below are files containing the code and face images from the in-class demo on PCA. For the demo I used Octave, which is a free alternative to MATLAB. See their website and the GNU Octave wiki for more info on how to download and use Octave.- eigenfaces.m contains the commands I used with some explanatory comments. You can open it with a text editor and copy and paste them into the octave command line.
- You will need faces.mat in your working directory in order to load the matrix of face images. These 14 images were taken from the Yale Face Database B.
