Although visible face recognition systems have grown as a major area of research, they are still facing serious challenges when operating in uncontrolled environments. In attempt to overcome these limitations, thermal imagery has been investigated as a promising direction to extend face recognition technology. However, the reduced number of databases acquired in thermal spectrum limits its exploration. Therefore, we introduce this database of face images acquired simultaneously in visible and thermal spectra under various variations: illumination, expression, pose and occlusion.
The presented database was acquired with a newly developed dual sensor, visible and thermal, camera FLIR Duo R by FLIR Systems. This camera is designed for unmanned aerial vehicle allowing to capture simultaneously images and videos in both visible and thermal spectra. Accordingly, it is well suited for our database collection aimed at fusion for face recognition as well as cross-spectrum applications. The visible sensor is a CCD sensor with a pixel resolution of 1920×1080. The thermal sensor of this camera is an uncooled VoX microbolometer and has a spectral response range of 7.5 - 13.5µm with a pixel resolution of 160×120.
