(formerly Olivetti Research Labs) (~3.7 MB) (~4 MB) 

See efg's Interactive PGMP5 "viewer" to display PGM files (P5 format) or the command-line utility ConvertFaces to convert PGM files of the Olivetti and Oracle Research Laboratory's Database of Faces (400 images) to BMP or JPG: PortableGrayMap.ZIP

Faces of 16 people, 27 of each person under various conditions of illumination, scale, and head orientation.     faceimages.tar.Z (~5.7 MB) 

The Yale Face Database (size 6.4MB) contains 165 grayscale images in GIF format of 15 individuals. There are 11 images per subject, one per different facial expression or configuration: center-light, w/glasses, happy, left-light, w/no glasses, normal, right-light, sad, sleepy, surprised, and wink. 

AR Face Database
This face database contains more than 130 people (around 70 males and 60 females). Everyone was asked to come twice to the Computer Vision Center, where the pictures were taken under strict controlled conditions. These two different sessions were separated in 14 days (two weeks time).

USC-SIPI Image Database University of Southern California Signal and Image Processing Institute:  The USC-SIPI image database is a collection of digitized images, which is maintained primarily to support research in image processing, image analysis, and machine vision. The first edition of the USC-SIPI image database was distributed in 1977 and many new images have been added since then.

Textures, high altitude aerial images, Lenna, baboon, other favorites, sequences (moving head, fly-overs, moving vehicles).
