ABSTRACT
Photographic film contains film-grain noise that translates to multiplicative, non-Gaussian noise in the exposure domain. A method based on the unscented Kalman filter can suppress this noise while simultaneously preserving edge information.
INDEX TERMS
film-grain noise, unscented Kalman filter, Markov random field (MRF), discontinuity adaptive MRFs, importance sampling
