Color image demosaicking: An overview

Demosaicking is the process of reconstructing a full-resolution color image from the sampled data acquired by a digital camera that apply a color filter array to a single sensor. This paper discusses the need of a color filter array and presents a survey of several techniques proposed to demosaicking. A comparison between the different methods is also provided, discussing their performances.

► Demosaicking is the reconstruction of a color image from the data acquired with a CFA.
► This paper presents a survey of several techniques proposed to demosaicking.
► The several demosaicking methods are subdivided into five categories.
► Also joint demosaicking and super-resolution or denoising techniques are described.
