说明： ORL人脸数据库
由剑桥大学AT&T实验室创建,包含40人共400张面部图像,部分志愿者的图像包括了姿态,
表情和面部饰物的变化.该人脸库在人脸识别研究的早期经常被人们采用,但由于变化模式较少,多数系统的识别率均可以达到90%以上,因此进一步利用的价值已经不大.
(ORL Face Database
Created by the AT&T Laboratory of Cambridge University, it contains 400 facial images of 40 people. Some of the volunteers'images include postures.
The face database is often used in the early stage of face recognition research, but because of the few change modes, the recognition rate of most systems can reach more than 90%, so the value of further utilization is not great.)

The ORL face database
---------------------
This directory contains a set of faces taken between April 1992 and
April 1994 at the Olivetti Research Laboratory in Cambridge, UK.
There are 10 different images of 40 distinct subjects. For some of the
subjects, the images were taken at different times, varying lighting
slightly, facial expressions (open/closed eyes, smiling/non-smiling)
and facial details (glasses/no-glasses). All the images are taken
against a dark homogeneous background and the subjects are in
up-right, frontal position (with tolerance for some side movement).
The files are in PGM format and can be conveniently viewed using the 'xv'
program. The size of each image is 92x112, 8-bit grey levels. The images
are organised in 40 directories (one for each subject) named as:
sX
where X indicates the subject number (between 1 and 40). In each directory
there are 10 different images of the selected subject named as:
Y.pgm
where Y indicates which image for the specific subject (between 1 and 10).
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:
