We introduce a method for hyperspectral unmixing that incorporates wavelength dependence in addition to spatial dependence. Spatial dependence is incorporated into the model using class labels on the pixels that is assigned using spectral clustering. Wavelength dependence is introduced by correlating the errors in the unmixing regression models. We propose a non-standard alternating direction m...

The emerald ash borer (EAB) is an exotic insect pest currently threatening ash species in the Great Lakes region. Because of the potential impact on forests in this area, multiple government agencies are currently focusing their efforts on developing new technologies to detect, monitor and control this insect pest. Previous work has shown that hyperspectral remote sensing technologies can produ...

The non-native Saltcedar (Tamarix ramosissima Ledeb.) and the native Honey mesquite (Prosopis Glandulosa Torr.), exist in abundance in Clark County, NV. We are using remote sensing to measure changes in distribution and abundance of these species. We collected six strips of 1m-resolution SpecTIR hyperspectral images in Clark County on May, 2005. SpecTIR has 227 spectral bands ranging from 0.45 ...

Hyperspectral remote sensing imagery contains much more information in the spectral domain than does multispectral imagery. The consecutive and abundant spectral signals provide a great potential for classification and anomaly detection. In this study, two real hyperspectral data sets were used for anomaly detection. One data set was an Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) da...

A textura tem grande importância no manejo dos solos, fazendo-se necessária a sua determinação, sendo razão de bandas espectrais estreitas pode ser uma alternativa rápida e precisa para este fim. Então o objetivo deste trabalho é avaliar uso dados espectrais, adquiridos pelo sensor aerotransportado SpecTIR-VS com pixel 1 m, na seleção duas composição melhor Índice por Diferença Normalizada, que...

Oil spill is one of major marine environmental challenges. The main impacts of this phenomenon are preventing light transmission into the deep water and oxygen absorption, which can disturb the photosynthesis process of water plants. In this research, we utilize SpecTIR airborne sensor data to extract and classify oils spill for the Gulf of Mexico Deepwater Horizon (DWH) happened in 2010. For t...

Introduction: A key goal for infrared remote sensing studies of Mars is to determine which minerals are present and absent. Visible/infrared spectroscopy is the primary method for remote mineral identification. In order to understand the resulting interpretations, it is necessary to understand the sources of uncertainty. Here we detail the primary uncertainties in the method. Interpretations of...
