conference on algorithms and Technologies for multispectral, hyperspectral, and Ultraspectral imagery XIX
作者: Theiler, James Wohlberg, Brendt Los Alamos Natl Lab Los Alamos NM 87545 USA
Gas-phase chemical plumes exhibit, particularly in the infrared, distinctive emission signatures as a function of wavelength. hyperspectral imagery can exploit this distinctiveness to detect specific chemicals, even a... 详细信息

conference on algorithms for multispectral and hyperspectral imagery
作者: GEE, SJ HUGHES AIRCRAFT CO DEPT IMAGE EXPLOITATEL SEGUNDOCA 90245
Image analysis is especially laborintensive in the multispectral domain due to the non-intuitive nature of the data. The data is frequently separated by frequency range into a set of image planes. For image analysts (... 详细信息

conference on algorithms for multispectral, hyperspectral, and Ultraspectral imagery VI
作者: Thornton, SS Moura, JMF Media Site Inc Pittsburgh PA USA
We have developed an adaptive anomaly detector based on a three-dimensional Gauss-Markov random field model (GMRF) for the background clutter in hyperspectral imagery. We have shown that incorporating the modeling fra... 详细信息
