We conduct an exhaustive survey of image thresholding methods, categorize them, express
their formulas under a uniform notation, and finally carry their performance comparison. The …

Adaptive binarization methods play a central role in document image processing. In this
work, an adaptive and parameterless generalization of Otsu's method is presented. The …

In this work, a multi-scale binarization framework is introduced, which can be used along
with any adaptive threshold-based binarization method. This framework is able to improve …

In this paper, we propose a novel binarization method for document images produced by
cameras. Such images often have varying degrees of brightness and require more careful …

The running maximum-minimum (max-min) filter computes the maxima and minima over
running windows of size w. This filter has numerous applications in signal processing and …

We study the routing problem for multi-hop wireless ad hoc networks based on cooperative
transmission. We prove that the minimum energy cooperative path (MECP) routing problem …

The demand for high-speed FPGA compilation tools has occurred for three reasons: first, as
FPGA device capacity has grown, the computation time devoted to placement and routing …

This paper addresses the problem of enhancing and restoring single-sided low-quality
single-sided document images. Initially, a series of multi-level classifiers is introduced …

The goal of this paper is to correct bleed-through in degraded documents using a variational
approach. The variational model is adapted using an estimated background according to the …

In this paper, we propose a new algorithm for the binarization of degraded document
images. We map the image into a 2D feature space in which the text and background pixels …
