Enhanced bleed through removal for scanned document images

Back-to-front interference is a common problem in documents, printed on translucent pages with insufficient opacity and is referred to as bleed through. The present state-ofart algorithms address bleed through based on entropy [1-3], entropic correlation [4] and discriminator analysis [5, 10]. However, a common drawback of such algorithms is their inefficient processing of documents that are ei...

Non-Local Patch-Based Image Inpainting

Image inpainting is the process of filling in missing regions in an image in a plausible way. In this contribution, we propose and describe an implementation of a patch-based image inpainting algorithm. The method is actually a two-dimensional version of our video inpainting algorithm proposed in [16]. The algorithm attempts to minimise a highly non-convex functional, first introducted by Wexle...

A Ground Truth Bleed-Through Document Image Database

This paper introduces a new database of 25 recto/verso image pairs from documents suffering from bleed-through degradation, together with manually created foreground text masks. The structure and creation of the database is described, and three bleed-through restoration methods are compared in two ways; visually, and quantitatively using the ground truth masks.

A Variational Framework for Non-local Image Inpainting

Non-local methods for image denoising and inpainting have gained considerable attention in recent years. This is in part due to their superior performance in textured images and regions, a known weakness of purely local methods. Local methods on the other hand have demonstrated to be very appropriate for the recovering of geometric structure such as image edges. The synthesis of both types of m...

Bleed-through removal in degraded documents

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...
