conference on algorithms for multispectral and hyperspectral imagery ii
作者: Carlotto, MJ PACIFIC SIERRRA RES CORP ARLINGTONVA 22209
The accurate classification of remotely sensed imagery usually requires some form of ground truth data. Maps are potentially a valuable source of ground truth but have several problems (e.g., they are usually out-date... 详细信息

作者: Umana-Diaz, Alejandra Velez-Reyes, Miguel Univ Puerto Rico Ctr Subsurface Sensing & Imaging Syst Lab Appl Remote Sensing & Image Proc POB 9048 Mayaguez PR 00681 USA
In hyperspectral imaging, the quality of the collected spectral signatures can be degraded by blurring due to the channel weighting function of the imaging spectrometer. In this work, we are investigating reconstructi... 详细信息
