Abstract

A universal demosaicking solution appropriate for imaging pipelines employing a red–green–blue (RGB) color filter array (CFA) is introduced. The proposed solution can demosaick a raw, grayscale, CFA sensor image captured by a digital camera equipped with any RGB-CFA currently in use. The solution utilizes a spectral model, an edge-sensing mechanism, and a postprocessor to preserve the coloration and sharpness of the captured image. The framework readably unifies existing demosaicking solutions which differ in design characteristics, performance, and computational efficiency. Simulation studies indicate that the universal demosaicking framework allows for cost-effective camera image processing and produces visually pleasing full-color digital images.
