Spectral Image Exploitation - SMACC®
http://www.spectral.com/SMACC.shtml
Software: Spectral Image Exploitation - SMACC. SSI is also active in the development of algorithms for spectral image exploitation, including target detection and classification. For example, SSI scientists developed SMACC (Sequential Maximum Angle Convex Cone), a fast, fully automated endmember-finding and unmixing algorithm that can be applied to multispectral as well as hyperspectral data. It is included as a spectral analysis tool in ENVI. Material abundance maps generated with SMACC.
