Denoising + Demosaicking

We propose new approaches to demosaicing of spatially sampled image data observed through a color filter array, in which the correlation of color components are exploited in order to reconstruct a subsampled image. Two frameworks for applying existing image denoising algorithms to color filter array data are developed—one for wavelet domain processing, and the other for pixel domain processing.
