Use of the SAR Shadowing Effect for Deforestation Detection with Sentinel-1 Time Series
To detect deforestation using Earth Observation (EO) data, widely used methods are based on the detection of temporal changes in the EO measurements within the deforested patches. In this paper, we introduce a new indicator of deforestation obtained from

Statistical Modeling of Shadows in SAR Imagery
Shadows are a special distortion in synthetic aperture radar (SAR) imaging. They often hamper proper image understanding and target recognition but also offer useful information, and therefore, the statistical modeling of SAR image shadows is imperative.

DARCLOS: a cloud shadow detection algorithm for TROPOMI [PDF]
Cloud shadows are observed by the TROPOMI satellite instrument as a result of its high spatial resolution compared to its predecessor instruments. These shadows contaminate TROPOMI's air quality measurements, because shadows are generally not taken into ...

Infants' perception of lightness changes related to cast shadows. [PDF]
When humans perceive the lightness of an object's surface in shadows there is an implicit assumption that cast shadows dim the surface. In two experiments, we investigated whether 5- to 8-month-old infants make this assumption about shadows. According to

The Shadow Effect on Surface Biophysical Variables Derived from Remote Sensing: A Review
In remote sensing (RS), shadows play an important role, commonly affecting the quality of data recorded by remote sensors. It is, therefore, of the utmost importance to detect and model the shadow effect in RS data as well as the information that is ...

ABSTRACT We investigate whether corporate insiders attempt to circumvent insider trading restrictions by using their private information to facilitate trading in economically linked firms, a phenomenon we call “shadow trading.” Using measures of informed trading to proxy for shadow trading, we find increased levels of informed trading ...
