conference on algorithms and Technologies for multispectral, hyperspectral, and Ultraspectral imagery XI
作者: Cisz, AP Schott, JR Rochester Inst Technol Digital Imaging & Remote Sensing Lab Rochester NY 14623 USA
Many different hyperspectral target detection algorithms have been developed and tested under various assumptions, methods, and data sets. This work examines the spectral angle mapper (SAM), adaptive coherence estimat... 详细信息

conference on algorithms for multispectral, hyperspectral, and Ultraspectral imagery VI
作者: Anderson, DS Keaffaber, B Wasky, R Veridian Engineering (United States)
In this paper, a process of converting hyperspectral (HSI) data to multispectral (MSI) data is described. Accomplishing this conversion involves several steps: (1) data-to-signal conversion using the modulation transf... 详细信息

conference on algorithms and Technologies for multispectral, hyperspectral, and Ultraspectral imagery XVI
作者: Daniel, Brian J. Schaum, Alan P. USN Res Lab Washington DC 20375 USA
The most widespread methods of anomaly detection in hyperspectral imagery (HSI) are the RX algorithm and its variants (e.g. Subspace RX). RX is optimal for any unimodal elliptically contoured distribution (ECD), and i... 详细信息

25th SPIE conference on algorithms, Technologies, and Applications for multispectral and hyperspectral imagery
作者: Metcalf, Jeremy P. Olsen, Richard C. Naval Postgrad Sch 833 Dyer Rd Monterey CA 93943 USA
Spectral LiDAR analysis can be enabled by the use of spatial context, spatial structure, and prior information in the form of map data. LiDAR intensity imagery are analyzed here using an object-based approach which se... 详细信息
