Abstract
A method for chroma denoising a digital image created in a digital camera includes decomposing the digital image into a plurality of spatial frequency bands. A separate modified color correction matrix is calculated from a color correction matrix associated with the camera for each of the plurality of spatial frequency bands. Each modified color correction matrix is applied to data in its corresponding spatial frequency band to produce color-corrected data in the plurality of spatial frequency bands. The color-corrected data in plurality of spatial frequency bands is combined to produce an output image.
