Interpolant-based demosaicing routines for dual-mode visible/near-infrared imaging systems

Abstract: 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.

“… 28 , consistent with the methods in Ref. 38 . (c) A bioinspired long-pass/short-pass camera (or bioinspired camera) makes two substitutions compared with an RGB-IR camera: First, it replaces the single layer of silicon photodiodes with three layers of such photodiodes (each sensitive to shorter wavelength, longer wavelengths, or intermediate wavelengths), and second, it replaces the layer of four different absorptive filters with a layer of two different interferences filters (each serving as a short-pass filter tuned for VIS light or a long-pass filter tuned for NIR light).…”

“…A family of demosaicing routines that is compatible with dual-mode visible/near-infrared imaging systems like the RGB-IR sensor and the bioinspired sensor but does not make assumptions on the correlation between the visible channels and the near-infrared channels has already been proposed in Ref. 38 . These demosaicing routines recognize that each channel is fully defined by a complicated function of two variables, the row number and column number, that can be locally approximated by much simpler interpolating polynomials taken in one of several variations.…”
