Outdoor Face Recognition Using Enhanced Near Infrared Imaging

In this paper, we present a robust and accurate system for outdoor (as well as indoor) face recognition, based on a recently developed enhanced near-infrared (ENIR) imaging device. Using a narrow band NIR laser generator instead of LED lights for active frontal illumination, the ENIR device can provide face images of good quality even under sunlight. Experiments show that the ENIR system performs similarly to the existing NIR system when used indoors, but outperforms it significantly outdoors especially under sunlight. Key words: Face recognition, near-infrared (NIR), imaging device, illumination, outdoor, statistical learning.
