Abstract

This paper presents a linear-based restoration method for bleed-through degraded document images and uses a Bayesian approach for bleed-through reduction. A variation of iterated conditional modes (ICM) optimisation is used whereby samples are drawn for the clean image estimates, whilst the remaining variables are estimated via the mode of their conditional probabilities. The proposed method is tested on various samples of scanned manuscript images with different degrees of degradation, and results visually compared with a recent user-assisted restoration method.
