Abstract
Image denoising techniques include determining wavelet-domain noise model and a non-parametric multivariate wavelet description from the image signal for raw image data. A noise corrected image may then be determined from the image signal, the wavelet-domain noise model and the non-parametric, multivariate wavelet description and the image signal.
