Algorithms and Technologies for Multispectral, Hyperspectral, and Ultraspectral Imagery XX.
The amount of hyperspectral imagery (HSI) data currently available is relatively small compared to other imaging modalities, and what is suitable for developing, testing, and evaluating spatial-spectral algorithms is virtually nonexistent. In this wo

Satellite Data Compression, Communications, and Processing IX.
The application of compression to hyperspectral image data is a significant technical challenge. A primary bottleneck in disseminating data products to the tactical user community is the limited communication bandwidth between the airborne sensor and

Over the past five years, the Air Force Research Laboratory and the Space Computer Corporation have supported the Civil Air Patrol in the development of the Airborne Real-time Cueing Hyperspectral Enhanced Reconnaissance (ARCHER) system, which combin

A novel approach to VNIR hyperspectral target identification is presented based on the Least-Angle Regression (LARS) variable selection and model building algorithm. The problem to be solved is that of accurately identifying a target's primary signat

A new endmember finder and spectral unmixing algorithm based on the LARS/Lasso method for linear regression is developed. The endmember finder is sequential; a single endmember is identified at first and further endmembers which depend on the previou

An adaptive algorithm is described for deriving constant false alarm rate (CFAR) detection thresholds based on statistically motivated models of actual spectral detector output distributions. The algorithm dynamically tracks the distribution of detec

A Generalized Likelihood Ratio (GLR) detector is formulated for a known spectral contrast signal that may be present with unknown amplitudes in a pair of co-registered hyperspectral image observations. Under multivariate Gaussian hypotheses, the join

Detection and Remediation Technologies for Mines and Minelike Targets IX.
Robust, timely, and remote detection of mines and minefields is central to both tactical and humanitarian demining efforts, yet remains elusive for single-sensor systems. Here we present an approach to jointly exploit multisensor data for detection o
