Spectral Angle Mapper as a Tool for Matching the Spectra in Hyperspectral Processing
Keywords:
hyperspectral imaging, noise, offset, spectral angle mapperAbstract
The article deals with analysis of Spectral Angle Mapper (SAM) as a tool for matching the separated endmembers with pure spectra from databases. The analysis of SAM is provided in three spectral regions: VIS, IR and VIS+IR together. Three kinds of available influences are analysed: additive noise, constant offset and slant offset.
