The Eigenfacebook

================

a Matlab GUI for creating a database of eigenface-profiles and accessing profiles using a login picture

Steps needed for eigenface approach

1. Assemble all photos into one mean-difference matrix M

2. Assemble the reference image into a mean-difference vector T

3. Obtain the projection matrix U from the SVD for M

4. Obtain the weight-score of U on M, ie U'*M

5. Obtain the weight-score of U on T, ie U'*T

6. Obtain the minimal Euclidean Distance between U'*T and U'*M, ie find min(sum((U'*M-U'*T).^2)).
