INTRODUCTION

This package implements basic Principal Component Analysis in Matlab and
tests is with grayscale portion of the FERET database. Images are not
preprocessed and it is up to the user to preprocess the images as wanted,
not changing the filenames.

"pca.m" and "createDistMat.m" can be used on any database following the 
same principles described in the header of the files. "feret.m" is specific
for the FERET database but can easily be transformed to be generic if needed.

In addition to the three .m files, standard FERET gallery and probe set lists
are given, along with a list of randomly chosen 500 images that can be used
for testing:

Training set: trainList.mat
Gallery: feretGallery.mat
Probe sets: fb.mat; fc.mat; dup1.mat; dup2.mat

GENERAL INSTRUCTIONS

Run the function pca to create a variable pcaProj.
Input variable pcaProj to the function createDistMat, thus creating a distance
matrix that you then use as an input to the function feret. See headers of
all three functions for more details. The sequence should look something like this:

>> load trainList.mat
>> pca ('C:/FERET_Normalised/', trainList, 200);
>> pcaDistMatCos = createDistMat(pcaProj, 'COS');
>> pcaResultsCOS = feret(pcaDistMatCos, 50);

>> pcaResultsCOS.perc(1)         % gives rank 1 result
>> plot(pcaResultsL1.cms)        % plots the CMS curve
