CONFLUENCE SATELLITE IMAGE CLASSIFICATION

open access: yesActa Scientiarum Polonorum. Formatio Circumiectus, 2017
Zbieg rzek jest definiowany jako punkt spotkania dwóch lub więcej rzek, które dają początek nowej rzece. To połączenie się rzek powoduje, że parametry geometryczne, szczególnie szerokość i kąt przecięcia kształtują się w zależności od charakterystycznych cech zlewających się rzek.

Generalized Correlation-Based Imaging for Satellites [PDF]

open access: yesSIAM Journal on Imaging Sciences, 2020
We consider imaging of fast moving small objects in space, such as low earth orbit satellites. The imaging system consists of ground based, asynchronous sources of radiation and several passive receivers above the dense atmosphere. We use the cross correlation of the received signals to reduce distortions from ambient medium fluctuations.

An Epipolar Resampling Method for Multi-View High Resolution Satellite Images Based on Block

open access: yesIEEE Access, 2021
As the basis of stereo observation, epipolar resampling is a critical technology for 3D reconstruction. With the development of the 3D reconstruction using multi-view satellite images, the epipolar resampling of the multi-view satellite images has become

Satellite image search in AgoraEO

open access: yesProceedings of the VLDB Endowment, 2022
The growing operational capability of global Earth Observation (EO) creates new opportunities for data-driven approaches to understand and protect our planet. However, the current use of EO archives is very restricted due to the huge archive sizes and the limited exploration capabilities provided by EO platforms.
