Journal ArticleDOI
Forecasting Zoonotic Infectious Disease Response to Climate Change: Mosquito Vectors and a Changing Environment.
Andrew W. Bartlow,Carrie A. Manore,Chonggang Xu,Kimberly Kaufeld,Sara Y. Del Valle,Amanda Ziemann,Geoffrey Fairchild,Jeanne M. Fair +7 more
TL;DR: There is an urgent need to study vector-borne diseases in response to climate change and to produce a generalizable approach capable of generating risk maps and forecasting outbreaks, and a strategy for coupling climate and epidemiological models for zoonotic infectious diseases is provided.
Journal ArticleDOI
Spatially Adaptive Hyperspectral Unmixing
TL;DR: Results show that the un Mixing residual error of each pixel's spectrum from real data, estimated from the spatially adaptive methodology, is reduced when compared to a global scale EM estimation and linear unmixing methodology.
Journal ArticleDOI
Spectral Variability of Remotely Sensed Target Materials: Causes, Models, and Strategies for Mitigation and Robust Exploitation
TL;DR: In this article, the spectral response for a given material exhibits considerable variability from a variety of causes: intrinsic, depending on the composition or morphology of the material, extrinsic (depending on the size of an object or the concentration of the materials), or environmental (due to illumination, atmospheric distortion, and so on).
Proceedings ArticleDOI
Iterative convex hull volume estimation in hyperspectral imagery for change detection
TL;DR: The Simplex Volume Estimation algorithm (SVE), which avoids potential hindrances by taking a geometrical approach to approximate the convex hull enclosing the data through identification of the simplex vertices (known as endmembers).
Journal ArticleDOI
Metrics of spectral image complexity with application to large area search
TL;DR: The concept of the linear mixture model is applied to the question of spectral image complexity at spatially local scales and the ultimate application here is large area image search without a priori information regarding the target signature.
