Shadow Detection and Compensation in Aerial Images using MATLAB

International Journal of Computer Applications, 2015
Recently, Kuo-Liang Chung presented an efficient algorithm uses the ratio of hue over intensity as the parameter to determine the coarse shadow map and then the local thresholding method (STS) in which it needs the different threshold levels which is comparatively more time consuming (and if the threshold is not proper then the resultant image is not ...

Illumination invariance and shadow compensation via spectro-polarimetry technique [PDF]

Optical Engineering, 2012
A major problem for obtaining target reflectance via hyperspectral imaging systems is the presence of illumination and shadow effects. These factors are common artefacts, especially when dealing with a hyperspectral imaging system that has sensors in the visible to near infrared region. This region is known to have highly scattered and diffuse radiance

Frequency and Phenotype of Coexisting Aquaporin‐4 and Autoimmune Encephalitis Autoantibodies

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Among 9457 aquaporin‐4 (AQP4) immunoglobulin G‐positive patients, 2071 underwent autoimmune encephalitis antibody testing and 85 (4%) had coexisting antibodies, most commonly cerebrospinal fluid glial fibrillary acidic protein‐IgG and N‐methyl‐D‐aspartate receptor‐IgG, or serum high‐titer GAD65‐IgG.

Molecular Diagnosis in Children With Febrile Seizures: Beyond the Conventional Clinical Classification

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Febrile seizures (FS) are currently classified as simple or complex primarily to describe seizure characteristics, with limited ability to identify the underlying etiology. We evaluated whether molecular diagnosis could complement conventional classification and improve the diagnosis and management of FS.

Investigating the Effect of Inclination Angle and the Influence of Scan Parameters on the Appearance and Thermal and Mechanical Properties of Filigree Tension Rods of LPBF‐Manufactured NiTi Shape‐Memory Alloys

Advanced Engineering Materials, EarlyView.
This article investigates the dependence of the properties on the manufacturing orientation in the form of the inclination angle to the build plate of LPBF‐fabricated NiTi rods with a diameter of 150–220 µm. Metallographic, chemical, thermal, and mechanical characterization show behavior under identical manufacturing conditions that ranges from ...

The Shadow of the Italian Colonial Experience: The Impact of Collective Emotions on Intentions to Help the Victims’ Descendants

International Journal of Conflict and Violence, 2010
Recalling the Italian colonial experience elicits the collective emotions of guilt, shame, and ingroup-focused anger. We expected that these emotions would predict different reparation intentions in favor of the colonized populations' descendants ...

Cryogenic Deformation Behavior of TiAl and Insights Into Embrittlement After High‐Temperature Exposure Combined With Secondary Ion Mass Spectroscopy of Near Surface Chemistry

Advanced Engineering Materials, EarlyView.
Near‐surface deuterium enrichment profiles for different microstructural types of TiAl after exposure at 700 °C in a heavy water‐containing environment. The deuterium levels are significantly higher than expected from natural occurrence, indicating that the heavy water dissociated during the exposure treatment and entered the specimens.
