Joint Spatial-Temporal Color Demosaicking

Demosaicking of the color CCD data is a key to the image quality of digital still and video cameras. Limited by the Nyquist frequency of the color filter array (CFA), color artifacts often accompany high frequency contents in the reconstructed images. This paper presents a general approach of joint spatial-temporal color demosaicking that exploits all three forms of sample correlations: spatial, spectral, and temporal. By motion estimation and …
