Code and data for: Interpolant-based demosaicing routines for dual-mode visible/near-infrared imaging systems

Dual-mode visible/near-infrared imaging systems, including a bioinspired
six-channel design and more conventional four-channel implementations,
have transitioned from a niche in surveillance to general use in machine
vision. However, the demosaicing routines that transform the raw images
from these sensors into processed images that can be consumed by humans or
computers rely on assumptions that may not be appropriate when the two
portions of the spectrum contribute different information about a scene. A
solution can be found in a family of demosaicing routines that utilize
interpolating polynomials and splines of different dimensionalities and
orders to process images with minimal assumptions.
