Image Exploitation Algorithms: SSI is active in the development of algorithms for spectral image exploitation, including use for 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 both multispectral and hyperspectral data. SMACC is included as a spectral analysis tool in ENVI, and is also available from SSI as a stand-alone code.
