Stamp detection in scanned documents

Annales UMCS, Informatica, 2010
The article presents current challenges in stamp detection problem. It is a crucial topic these days since more and more traditional paper documents are being scanned in order to be archived, sent through the net or just printed. Moreover, an electronic version of paper document stored on a hard drive can be taken as forensic evidence of possible crime.

Detecting novel scans through pattern anomaly detection [PDF]

Proceedings DARPA Information Survivability Conference and Exposition, 2004
We introduce a technique for detecting anomalous patterns in a categorical feature (one that takes values from a finite alphabet). It differs from most anomaly detection methods used to date in that it does not require attack-free training data, and it improves upon previous methods known to us in that it is aware when it is adequately trained to ...

Guidelines for Pediatric Radiotherapy Simulation: A Report From the Children's Oncology Group Radiation Oncology Discipline

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.

Mobile Laser Scanning for Road Pavement Distress Detection

IEEE Open Journal of Intelligent Transportation Systems
This study investigates the efficacy of Mobile Laser Scanning (MLS) for detecting pavement distresses from precise 3D point cloud data. A conventional MLS system was evaluated against a high-accuracy pavement mapping reference system. The study data were

T2* Magnetic Resonance Imaging Uncovers Hemosiderin Burden in Pediatric Hemophilia: A Call for Sensitive Imaging Biomarkers

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Hemophilic arthropathy remains the leading morbidity in hemophilia despite modern prophylaxis, and early joint damage may be missed by routine exams. This study explored T2* MRI as a noninvasive biomarker of hemosiderin deposition in pediatric hemophilia.

The Relationship Between Physical Activity and Left Ventricular Remodeling in Childhood Cancer Survivors Treated With Anthracyclines: A Cross‐Sectional Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Anthracycline‐related cardiac remodeling precedes heart failure in childhood cancer survivors. The objectives of this study were to determine the relationships between patient‐specific factors, moderate‐to‐vigorous physical activity (MVPA), and cardiac remodeling.

Clinical, Histopathological, and Molecular Characterization of Pediatric MN1::ZNF341‐Associated Cancer

Pediatric Blood &Cancer, EarlyView.
ABSTRACT A lethal round‐cell malignancy with an MN1::ZNF341 fusion has recently been reported in three infants. Here, we describe four further tumors, three in newborns (including monozygotic twins), and one in an adolescent. Detailed clinical, radiological, and histopathological data differentiate these tumors from their main mimics, neuroblastoma and

Plasmonic near-field scanning nanoscope with a cross-polarization detection technique

Nanophotonics, 2019
A cross-polarization detection technique was introduced to enhance the signal-to-noise ratio (SNR) of a plasmonic near-field scanning nanoscope (PNSN) using the anisotropic reflection from a metallic ridge nano-aperture.
