Description of the Collection of Facial Images
You may freely download this data for your own exclusive
research purposes. You should publish computer recognition
results achieved on this data, with due
acknowledgement. You may not
publish/print/sell/distribute the images themselves.
I have provided my database in order to encourage comparative research.
Biometric processing comparisons and summary results are the main purpose.
I am not trying to be difficult by placing conditions on other uses.
However, I do not hold signed release forms from all the individuals
in this database. Therefore, strictly speaking, the rights to the display
of these images rest with the individuals depicted in them. I hope this
clarifies the legal position.
The data is held in four directories ( faces94
, faces95 , faces96
, grimace ), in order of increasing
difficulty. Faces96 and grimace are the most difficult, though for
two different reasons (variation of background and scale, versus extreme
variation of expressions).
For your convenience of downloading, there are zipped versions of all
the data in each directory. The images are stored in 24 bit RGB, JPEG format.
Total number of individuals: 395
Number of images per individual: 20
Total number of images: 7900
Gender: contains images of male and female subjects
Race: contains images of people of various racial origins
Age Range: the images are mainly of first year undergraduate
students, so the majority of indivuals are between 18-20 years old but
some older individuals are also present.
Image format: 24bit colour JPEG
Camera used: S-VHS camcorder
Lighting: artificial, mixture of tungsten and fluorescent overhead
