Cross talk (or show-through) interference is a common occurrence when scanning duplex printed documents. The back-side printing shows through the paper thus contaminating the front side image. Previous work focused on modelling the non-linear process and offered a simple adaptive decorrelation process. We propose an improved cleaning process. We take into account local brightness variations, estimating local background brightness through a mean-shift process and adapting to it. The effects of cross interference are minimized by a post processing adaptive filtering stage. Further improvement is achieved by a cascaded multi-stage filtering scheme.
