Face recognition algorithms need to deal with variable
lighting conditions. Near infrared (NIR) image based face
recognition technology has been proposed to effectively
overcome this difficulty. However, it requires that the enrolled
face images be captured using NIR images whereas
many applications require visual (VIS) images for enrollment
templates. To take advantage of NIR face images for
illumination-invariant face recognition and allow the use of
VIS face images for enrollment, we encounter a new face
image pattern recognition problem, that is, heterogeneous
face matching between NIR versus VIS faces.
In this paper, we present a subspace learning framework
named Coupled Spectral Regression (CSR) to solve this
challenge problem of coupling the two types of face images
and matching between them. CSR first models the properties
of different types of data separately and then learns two
associated projections to project heterogeneous data (e.g.
VIS and NIR) respective...
