A Natural Visible and Infrared facial Expression Database

The Key Laboratory of Computing and Communication Software of Anhui Province(CCSL) has constructed the USTC-NVIE (Natural Visible and Infrared facial Expression) database under the sponsor of the 863 project. To date, most facial expression analysis has been based on visible and posed expression databases. Visible images, however, are easily affected by illumination variations, while posed expressions differ in appearance and timing from natural ones. We propose and establish a natural visible and infrared facial expression database, which contains both spontaneous and posed expressions of more than 100 subjects, recorded simultaneously by a visible and an infrared thermal camera, with illumination provided from three different directions. The posed database also includes expression image sequences with and without glasses.
