Abstract
Chrominance data channels are reconstructed from a color-mosaic image data input and de-noised with guidance from a luminance data channel extracted from that same mosaic data input to produce de-noised chrominance channels. The de-noised chrominance channels are combined with a de-noised version of the luminance channel to yield a primary-color-channel output image.
