Target-based Hyperspectral Demixing via Generalized Robust PCA
Sirisha Rambhatla, Xingguo Li, Jarvis Haupt
Localizing targets of interest in a given hyperspectral (HS) image has applications ranging from remote sensing to surveillance. This task of target detection leverages the fact th…
A Dictionary-Based Generalization of Robust PCA Part II: Applications to Hyperspectral Demixing
Sirisha Rambhatla, Xingguo Li, Jineng Ren +1
We consider the task of localizing targets of interest in a hyperspectral (HS) image based on their spectral signature(s), by posing the problem as two distinct convex demixing tas…
Anomaly-Sensitive Dictionary Learning for Unsupervised Diagnostics of Solid Media
Jeffrey M. Druce, Jarvis D. Haupt, Stefano Gonella
This paper proposes a strategy for the detection and triangulation of structural anomalies in solid media. The method revolves around the construction of sparse representations of…
Automated Defect Localization via Low Rank Plus Outlier Modeling of Propagating Wavefield Data
Stefano Gonella, Jarvis D. Haupt
This work proposes an agnostic inference strategy for material diagnostics, conceived within the context of laser-based non-destructive evaluation methods, which extract informatio…
Level Set Estimation from Compressive Measurements using Box Constrained Total Variation Regularization
Akshay Soni, Jarvis Haupt
Estimating the level set of a signal from measurements is a task that arises in a variety of fields, including medical imaging, astronomy, and digital elevation mapping. Motivated…
