摘要：
Light fields are four-dimensional parametrizations of rays, extensively used for the representation of the rays emitted from three-dimensional objects. With the increasing availability of spectral imagers, conventional light fields can be augmented by the additional spectral information, yielding a five-dimensional ray parametrization referred to as a spectral light field. We demonstrate that utilization of the spectral channel information can improve the profilometric performance of light-field cameras.
