TLDR
Experimental results show that the new edge adaptive color demosaicing method for Bayer pattern images of single-sensor digital cameras achieves both higher signal fidelity and higher visual image quality as compared with some existing schemes.Abstract:
A new edge adaptive color demosaicing method for Bayer pattern images of single-sensor digital cameras is presented in this paper. An edge direction detector for narrow edges is proposed by making full use of inter-channel correlation to determine edge directions within the smallest detection radius. A combinative criterion is then formulated to cater for the diversity of edge occurrence in real-world scenes. The improvement of the proposed demosaicing scheme is achieved by an effective detection on edge directions, emphasizing on green channel restoration and the overall refinement. Experimental results show that the new scheme preserves better edge details, reduces color aliasing artifacts, and achieves both higher signal fidelity and higher visual image quality as compared with some existing schemes.read more

Demosaicing: image reconstruction from color CCD samples
TL;DR: The answer is to let the edges support the color information, and the color channels support the edges, and thereby achieve better perceptual results than those that are bounded by the sampling theoretical limit.
