Enhancing the durational enhancement of a tone contrast [PDF]
The Journal of the Acoustical Society of America, 2006 In central and low Franconian dialects of German and Dutch, a lexical tone contrast (accent 1 versus accent 2) exists that is enhanced by a durational difference. While pitch differences vary according to intonation and sentence context, syllables are generally shorter when they have accent 1.

Early Contrast Enhancement: a novel Magnetic Resonance Imaging biomarker of pleural malignancy [PDF]
, 2018 Introduction: Pleural Malignancy (PM) is often occult on subjective radiological assessment. We sought to define a novel, semi-objective Magnetic Resonance Imaging (MRI) biomarker of PM, targeted to increased tumour microvessel density (MVD) and ...

Effective Guided Image Filtering for Contrast Enhancement
IEEE Signal Processing Letters, 2018 Although the guided image filtering (GIF) has an excellent edge-preserving property, it is prone to suffer from the halo artifacts near the edges. Weighted GIF and gradient-domain GIF try to address the problem by incorporating an edge-aware weighting ...

Chemical enhancement of footwear impressions in blood on fabric:part 3: amino acid staining [PDF]
, 2013 Enhancement of footwear impressions, using ninhydrin or ninhydrin analogues is not considered common practice and such techniques are generally used to target amino acids present in fingermarks where the reaction gives rise to colour and possibly ...

Contrast-enhanced endoscopic ultrasound
Endoscopic Ultrasound, 2012 The European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB) introduced guidelines on the use of contrast-enhanced ultrasound (CEUS) in 2004. This EFSUMB-document focused mainly on liver applications. However, new applications extending beyond the liver were developed thereafter.

Contrast Enhancement Estimation for Digital Image Forensics [PDF]
ACM Trans. Multim. Comput. Commun. Appl., 2017 Inconsistency in contrast enhancement can be used to expose image forgeries. In this work, we describe a new method to estimate contrast enhancement operations from a single image.

Contrast-enhanced ultrasound of the pancreas [PDF]
World Journal of Radiology, 2010 The introduction of contrast-enhanced ultrasonography (CEUS) has led to major improvements in the diagnostic capabilities of ultrasound (US). The innovative use of CEUS for study of the pancreas has created the need for a definition of the most frequent dynamic features of solid and cystic masses.
