DUTransUNet: dual-decoder transformer U-net for differential interferogram deformation regions segmentation

Geocarto International
Differential Interferometric Synthetic Aperture Radar (DInSAR) is widely used for surface deformation monitoring. However, automatic segmentation of deformation regions in differential interferograms remains challenging because deformation-related ...

Monitoring Lakes in Mountains with Sentinel-1 SAR Imagery

Remote Sensing
Lakes are crucial markers of climate fluctuations, yet identifying water bodies in mountainous regions remains a persistent challenge for satellite remote sensing due to terrain-induced obstacles and dynamic surface conditions of ice and snow. We present

Spectral imaging as a potential tool for optical sentinel lymph node biopsies

We investigate the potential use of spectral imaging for performing an optical sentinel lymph node biopsy. Dummy images generated from previously published data are analysed using a spectral angle map and we conclude that there is scope for spectral ...

Soil moisture estimation underneath crop cover using high incidence angle C-band Sentinel-1 SAR data

Kuwait Journal of Science
SAR's return signal sensitivity to dielectric constant and penetration through vegetation makes it ideal for large-scale soil moisture studies. High incidence angle SAR data is especially useful for understanding crop characteristics.
