This review provides a comprehensive view of the field of historical document image
binarization with a focus on the contributions made in the last decade. After the introduction …

A detailed survey about the principles of image binarization techniques is introduced in this
chapter. A comprehensive review is given. A number of classical methodologies together …

Binarization plays an important role in document image processing, particularly in degraded
document images. Among all local image thresholding algorithms, Sauvola has excellent …

In this paper, a phase-based binarization model for ancient document images is proposed,
as well as a postprocessing method that can improve any binarization method and a ground …

For the purpose of facilitating benchmark contributions for binarization methods, a new fast
ground truthing approach, called the PhaseGT, is proposed. This approach is used for …

Inspired by the classic Sauvola local image thresholding approach, we systematically study
it from the deep neural network (DNN) perspective and propose a new solution called …

Binarization of historical documents is difficult and is still an open area of research. In this
paper, a new binarization technique for document images is presented. The proposed …

Document image binarization is often a challenging task due to various forms of
degradation. Although there exist several binarization techniques in literature, the binarized …

Adaptive binarization has been widely used in binarizing degraded document images. Most
of the adaptive methods, however, face two challenging problems: expensive computation …

Binarization of ancient degraded document images is a very important step for their
preservation and digital use. In this paper, a new simple threshold-based method is …
