Color Demosaicing of RGBW Color Filter Array Based on Laplacian Pyramid

Sensors, 2022
In recent years, red, green, blue, and white (RGBW) color filter arrays (CFAs) have been developed to solve the problem of low-light conditions. In this paper, we propose a new color demosaicing algorithm for RGBW CFAs using a Laplacian pyramid.
