Color Demosaicing of RGBW Color Filter Array Based on Laplacian Pyramid

Color Demosaicing of RGBW Color Filter Array Based on Laplacian Pyramid

Show other versions (1)

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. Because the white channel has a high correlation to th...
