FACES

Read Olivetti face database

   A = FACES(SUBJECTS,PHOTOS)

This creates a dataset A containing the desired photos (92*112 pixels)  of the desired subjects (1 <= SUBJECTS <= 40). For each subject 10 photos are available (1 <= PHOTOS <= 10). SUBJECTS and PHOTOS may  be vectors.  The size of A is (LENGTH(SUBJECTS)*LENGTH(PHOTOS),92*112).  The stored photos can be displayed by SHOW(A).

FACES first reads a datafile ORL and then converts it to a dataset.  In case ORL is not available, it may be automatically downloaded  and installed. If this fails an error is generated.

When using these images, please give credit to Olivetti Research Laboratory.  A convenient reference is the face recognition work which uses some of  these images
