HSI takes highly detailed spatial and spectral measurements of terrestrial scenes, which can be used to remotely infer which materials are present and in what quantities. This procedure of extracting material abundances, when the pure material spectra is known, is referred to as spectral unmixing. This talk will cover how sparsity based techniques can be utilized in spectral unmixing to not only uncover the material abundances but to also extract the pure material spectra from example HSI data. Additionally, this talk will cover how recent algorithms in spatial filtering algorithms based on sparse statistics can further improve spectral unmixing.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ESpeaker Bio:\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EAdam Charles received his undergraduate and master\u0027s degree in electrical engineering from The Cooper Union for the Advancement of Science and Art.
