Face recognition using Eigenfaces

The only images that this package accepts are .pgm (portable gray map) images. All images should be of the same size.
Training:
A training set of face images is needed to train the system. These images should be placed in a single folder in Matlab path.
Use the following function to train:
[images,H,W,M,m,U,omega]=trainingEF(trainingFolder);
where

trainingFolder - full path of the folder containing the training face images

Recognition:
The face image to be recognized should be a .pgm file too.

Use the following function for recognition:
testingEF(testImage,images,H,W,M,m,U,omega)

where
testImage - filename of the face image to be recognized (with extension),
images,H,W,M,m,U,omega - output arguments from the training function

The test image and the image from the training set that the test image corresponds to are shown as output.
