- 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:
- F. Samaria and A. Harter
- "Parameterisation of a stochastic model for human face identification"
- 2nd IEEE Workshop on Applications of Computer Vision
- December 1994, Sarasota (Florida).
- The paper is available via anonymous ftp from quince.cam-orl.co.uk and is
- stored in pub/users/fs/IEEE_workshop.ps.Z
- If you have any question, please email Ferdinando Samaria: fs@cam-orl.co.uk
