Extracting Filaments Based on Morphology Components Analysis from Radio Astronomical Images

Advances in Astronomy, 2019
Filaments are a type of wide-existing astronomical structure. It is a challenge to separate filaments from radio astronomical images, because their radiation is usually weak. What is more, filaments often mix with bright objects, e.g., stars, which makes

Automatic detection of ship tracks in ATSR-2 satellite imagery [PDF]

Atmospheric Chemistry and Physics, 2009
Ships modify cloud microphysics by adding cloud condensation nuclei (CCN) to a developing or existing cloud. These create lines of larger reflectance in cloud fields that are observed in satellite imagery.
