Deformation monitoring with Sentinel-1 Wave mode data
Piyush S. Agram, Matthew T. Calef, Kelly M. Olsen +2
We describe the salient characteristics of Sentinel-1 wave (WV) mode vignettes. We describe our approach for working with WV mode data that enables vignette-based data access and p…
Merging Point Data for InSAR Deformation Processing
Matthew T. Calef, Kelly M. Olsen, Piyush S. Agram
Given a collection of points , which is partitioned into overlapping subsets , and approximate data associated with t…
On the Detectability of Conflict: a Remote Sensing Study of the Rohingya Conflict
Christopher X. Ren, Matthew T. Calef, Alice M. S. Durieux +2
The detection and quantification of conflict through remote sensing modalities represents a challenging but crucial aspect of human rights monitoring. In this work we demonstrate h…
BUDD: Multi-modal Bayesian Updating Deforestation Detections
Alice M. S Durieux, Christopher X. Ren, Matthew T. Calef +2
The global phenomenon of forest degradation is a pressing issue with severe implications for climate stability and biodiversity protection. In this work we generate Bayesian updati…
Feature Augmentation Improves Anomalous Change Detection for Human Activity Identification in Synthetic Aperture Radar Imagery
Hannah J. Murphy, Christopher X. Ren, Matthew T. Calef
Anomalous change detection (ACD) methods separate common, uninteresting changes from rare, significant changes in co-registered images collected at different points in time. In thi…
Estimating the Number of Stable Configurations for the Generalized Thomson Problem
Matthew Calef, Whitney Griffiths, Alexia Schulz
Given a natural number N, one may ask what configuration of N points on the two-sphere minimizes the discrete generalized Coulomb energy. If one applies a gradient-based numerical…
