yalefaces.tar.gz       The original dataset from YALE.tar.gz
    faces/                 The original dataset in PGM format.
    matlab/                Code used to process the original YALE dataset
    rotated/               Faces rotated so eyes are aligned horizontally
    centered/              Rotated faces cropped and middle of eyes centered.
    unpadded/              Centered faces cropped out
    supported/             Unpadded faces shrunk and outline blanked out
    eigfaces/              Unpadded faces gone through SVM as arrays of floats
    eigfaces-for-your-vie  The above as PGMs (not suitable for processing as
                           they have undergone rescaling by matlab)
    eyelocs.mat            Locations of eyes
    eyedistances.dat       Distances between eyes
    support-trapezoid.pgm  The support map used
    support.pgm            An alternative support map which preserves more pixels
    eigenvalues.dat        The computed eigenvalues
