This paper presents a new adaptive approach for the binarization and enhancement of degraded documents. The proposed method does not require any parameter tuning by the user and can deal with degradations which occur due to shadows, non-uniform illumination, low contrast, large signal-dependent noise, smear and strain. We follow several distinct steps: a pre-processing procedure using a low-pas...

Document Image Binarization is performed in the preprocessing stage for document analysis and it aims to segment the foreground text from the document background. A fast and accurate document image binarization technique is important for the ensuing document image processing tasks such as optical character recognition (OCR) and Document Image Retrieval (DIR). This research area has been studied...

Extremely low-quality images, on the order of 20 pixels in width, appear with frustrating frequency in many forensic investigations. Even advanced de-noising and super-resolution technologies are unable to extract useful information from such lowquality images. We show, however, that useful information is present in such highly degraded images. We also show that convolutional neural networks ca...

The potential of different field boundary types in lowland farmland to contribute to arthropod biodiversity and sustainable agriculture was investigated. Field boundaries, categorised according to nationally applicable definitions, were found to represent ecologically differing habitats based on their woody abundance and the frequency of young and mature emergent trees. These habitat characteri...

In the process of service, reinforced concrete structures have to bear both load and multi-environmental factors. The deterioration beams is critical durability, safety, sustainability structures. main aim present research determine degradation mechanism subjected sustained loading Reinforced beam specimens were prepared, loaded then exerted At end each period, (chemical contents surfaces, carb...

This paper presents the initial results from a study into the interaction between safety culture and degraded modes of operation in European Air Traffic Management (ATM). Degraded modes occur when operators struggle to maintain levels of service even though key elements of their infrastructure have failed. Safety culture can be simply described as ‘the way safety is done around here’ – emphasiz...

Thanks to the incorporation of robotic systems, the development of industrial processes has generated a great increase in productivity, yield and product quality. Nevertheless, as far as technological advancement permits a greater automation level, system complexity also increases, with greater number of components, therefore rising the probability of failures or anomalous operation. This can r...

In this paper we address the problem of complex events in degraded image sequences. The occurrence of these complex events causes the failure of the motion estimation process. Consequently, the sequence of operations that rely on it, such as motion compensation and motion picture restoration, will fail as well. We present a statistical analysis of such areas, as well as a taxonomy of pathologic...

Sound source localization and separation with permutation resolution are essential for achieving a computational auditory scene analysis system that can extract useful information from a mixture of various sounds. Because existing methods cope separately with these problems despite their mutual dependence, the overall result with these approaches can be degraded by any failure in one of these c...
