In hyperspectral imaging, hundreds of images are taken at narrow and contiguous spectral bands providing us with high spectral resolution spectral signatures that can be used to discriminate between objects. In many ...

Brain Computer Interface (BCI) is a system that is designed to translate a subject’s thought into a signal that is interpreted by a device. A BCI provides a communication channel between the human brain and a computer, ...

This dissertation proposes a spatially adaptive constrained Nonnegative Matrix Factorization (sacNMF) for unmixing of hyperspectral imagery. The image is decomposed into spectrally homogeneous regions using quadtree region ...
