abstract = {The extended Yale Face Database B contains 16128 images of 28 human subjects under 9 poses and 64 illumination conditions. The data format of this database is the same as http://cvc.yale.edu/projects/yalefacesB/yalefacesB.html the Yale Face Database B. Please refer to the homepage of the Yale Face Database B for more detailed information of the data format. 

You are free to use the extended Yale Face Database B for research purposes. All publications which use this database should acknowledge the use of "the Exteded Yale Face Database B" and reference Athinodoros Georghiades, Peter Belhumeur, and David Kriegman's paper, "From Few to Many: Illumination Cone Models for Face Recognition under 
Variable Lighting and Pose", PAMI, 2001. 

The extended database as opposed to the original Yale Face Database B with 10 subjects was first reported by Kuang-Chih Lee, Jeffrey Ho, and David Kriegman in "Acquiring Linear Subspaces for Face Recognition under Variable Lighting, PAMI, May, 2005 http://vision.ucsd.edu/~leekc/papers/9pltsIEEE.pdf All test image data used in the experiments are manually aligned, cropped, and then re-sized to 168x192 images.
If you publish your experimental results with the cropped images, please reference the PAMI2005 paper as well.}
