PCA Face Recognition
MatLab implementation
http://www.vision.ime.usp.br/~teo/pca
_________________________________________________
Instructions:
1 - Open file pca.m.
2 - Read its comments and replace the "???"
to the parameters that you have to set
(location of face image database,
number of eigenfaces, etc).
3 - Script pca.m uses the functions resize.m,
loadpop.m, makebasis.m, classif.m and
success.m. You can learn a little bit
about them by reading the script pca.m.
4 - The purpose of function showimg.m is to
plot the images. Function pca.m does not
call it.
5 - All the functions have descriptions and
you can see them by typing
"help " in the MatLab's
command line.
6 - For the face image database, I recommended
that:
* your image database contains only the
images that you will use for training
and testing the PCA face recognition
system;
* all the people have the same number of
images in the database;
* the file names be like xxx_yyy, where
xxx is the number of the person of this
file and yyy is the number of this sample
image of that person.
7 - After setting the correct paramethers
in the script pca.m, you can run it and
it will perform the training of a PCA
system and a recognition process.
I hope you enjoy it!
If you have any problem, suggestion, comments
or if you improved this version, please contact me.
