At the Weizmann Institute of science we constructed a very well
controlled database of faces (Yael Moses,
yael@wisdom.weizmann.ac.il). It includes variations due to changes in
viewpoint (mainly horizontal), illumination (only horizontal), and
three different expressions. 

The database of faces  can be found  in two sites:
1. ftp ftp.wisdom.weizmann.ac.il
   (as anonymous)
   cd edelman/disk3

2. ftp ftp.eris.weizmann.ac.il
   (as anonymous)
   cd pub/FaceBase

Between the two sites you will find all the images.

There are about 28 faces.
The name of the files are as follows:

name-vp?-il?-ex?

where vp?  ?={0,1,2,3,4},
where il?  ?={0,1,2,3}
where ex?  ?={0,1,2}

For some il and ex there are more vp, you can 'ls' on a name and see.

The images are compressed and  in a raw format with size 512x352.
The pixels are not squares but have a ratio x:y 12:11.

If you need any assistant, I will be happy to help.
Please let me know if anything interesting came out of it.
