A 15-year circum-Antarctic iceberg calving dataset derived from continuous satellite observations [PDF]

Earth System Science Data, 2021
Iceberg calving is the main process that facilitates the dynamic mass loss of ice sheets into the ocean, which accounts for approximately half of the mass loss of the Antarctic ice sheet.

Shannon Entropy for the $\mathcal {G}^0_I$ Model: A New Segmentation Approach

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
Synthetic aperture radar (SAR) has been successfully used as a remote sensing tool. However, SAR images are contaminated by speckle noise and require specialized postprocessing procedures; e.g, tailored segmenters.

Land Subsidence Monitoring in Greater Vancouver Through Synergy of InSAR and Polarimetric Analysis

Canadian Journal of Remote Sensing, 2018
Up-to-date spatial information on ground movements and land use is useful for emergency management of coastal regions. Time series InSAR techniques have proven to be effective tools for providing the former; however, InSAR results alone cannot be used to

Multidimensional Speckle Noise Model

EURASIP Journal on Advances in Signal Processing, 2005
One of the main problems of SAR imagery is the presence of speckle noise, originated by the inherent coherent nature of this type of systems. For one-dimensional SAR systems it has been demonstrated that speckle can be considered as a multiplicative ...
