Analysis of camouflage cover spectral characteristics by imaging spectrometer

Error Analysis of Spectral Reflectance Derived from Imaging Spectrometer Data’

As the field of remote imaging spectrometry grows, interest increases in applications that require the data be “corrected” to surface reflectance. However, the utility of the data for these applications will be limited by the accuracy to which the correction can be performed. Two approaches to atmospheric compensation are reviewed and applied to airbome spectrometer data to study their error ch...

Land Cover Classification with the Medium Resolution Imaging Spectrometer (meris)

The Medium Resolution Imaging Spectrometer (MERIS) is a payload component of Envisat-1. MERIS is operated over land with a standard 15 band setting acquiring images in the VIS and NIR part of the electromagnetic spectrum. Data are acquired at 300 m (full resolution) and 1,200 m (reduced resolution) spatial resolution over land, thus vegetation can be monitored at regional to global scales. The ...

Band-Moment Analysis of Imaging- Spectrometer Data

Modern sensor systems high in spectral resolution, such as the Airborne Imaging Spectrometer (AIS), are challenging from an image-processing standpoint because direct classification of datasets with 100 or more spectral channels is virtually impossible. Thus, it is necessary to conduct pre-classification manipulations and transformations both to reduce the amount of data to be classified and to...

Evaluation criteria for spectral design of camouflage

Differential diagnosis of pancreatic cystic masses with the quantitative analysis of spectral CT imaging: Initial results

Background: To retrospectively evaluate whether quantitative information derived from spectral imaging can improve the differential diagnosis of pancreatic cystic masses including pancreatic solid pseudopapillary epithelial neoplasms (SPENs), mucin- producing cysts and pseudocysts. Materials and Methods: From June 2015 to October 2017, 56 patients (22 pseudocysts, 18 mucin-producing cysts and 1...
