<H2>Data Format</H2>
<P>The image data can be found in /faces. This directory contains 20 subdirectories, one for each person, named by userid. Each of these directories contains several different face images of the same person.
</P>
<P>
You will be interested in the images with the following naming convention:
</P>
<blockquote>
<tt> <userid> <pose> <expression> <eyes> <scale>.pgm </tt>
</blockquote>
<UL>
<li> <tt><userid></tt> is the user id of the person in the image, and this field has 20 values: an2i, at33, boland, bpm, ch4f, cheyer, choon, danieln, glickman, karyadi, kawamura, kk49, megak, mitchell, night, phoebe, saavik, steffi, sz24, and tammo. </li>
<li> <tt><pose></tt> is the head position of the person, and this field has 4 values: straight, left, right, up. </li>
<li> <tt><expression></tt> is the facial expression of the person, and this field has 4 values: neutral, happy, sad, angry. </li>
<li> <tt><eyes></tt> is the eye state of the person, and this field has
2 values: open, sunglasses. </li>
<li> <tt><scale></tt> is the scale of the image, and this field has 3 values: 1, 2, and 4. 1 indicates a full-resolution image (128 columns by 120 rows); 2 indicates a half-resolution image (64 by 60); 4 indicates a quarter-resolution image (32 by 30).</li>
</UL>
<P>If you've been looking closely in the image directories, you may notice
that some images have a <tt>.bad</tt> suffix rather than the <tt>.pgm</tt>
suffix. As it turns out, 16 of the 640 images taken have glitches due to
problems with the camera setup; these are the <tt>.bad</tt> images.
Some people had more glitches than others, but everyone who got ``faced''
should have at least 28 good face images (out of the 32 variations
possible, discounting scale).
