Oulu-CASIA NIR&VIS facial expression database
Oulu-CASIA NIR&VIS facial expression database contains videos with the six typical expressions (happiness, sadness, surprise, anger, fear, disgust) from 80 subjects captured with two imaging systems, NIR (Near Infrared) and VIS (Visible light), under three different illumination conditions: normal indoor illumination, weak illumination (only computer display is on) and dark illumination (all lights are off).
Here is the document for the database collection information. The database can be used, for example, in studying the effects of illumination variations to facial expressions, cross-imaging-system facial expression recognition or face recognition.
This database now is released. If you are interested, please contact Dr. Guoying Zhao
