This paper deals with a new problem in face recognition
research, in which the enrollment and query face samples
are captured under different lighting conditions. In our
case, the enrollment samples are visual light (VIS) images,
whereas the query samples are taken under near infrared
(NIR) condition. It is very difficult to directly match the
face samples captured under these two lighting conditions
due to their different visual appearances. In this paper, we
propose a novel method for synthesizing VIS images from
NIR images based on learning the mappings between
images of different spectra (i.e., NIR and VIS). In our
approach, we reduce the inter-spectral differences
significantly, thus allowing effective matching between
faces taken under different imaging conditions. Face
recognition experiments clearly show the efficacy of the
proposed approach.
