Example based demosaicing

Demosaicing is an algorithm used to reconstruct a color image from the incomplete color samples of a color filter array (CFA). Most demosaicing algorithms can be broadly classified into spatial-domain and frequency-domain approaches. Despite significant progress in the past decade, current state of the art demosaicing algorithms still tend to produce artifacts at high-saturation edges. In this paper we propose a new approach to demosaicing - example based. Comparative experimental evaluation shows that example-based demosaicing (EBD) produces visually superior, artifact-free results.
