SIAM Journal on Imaging Sciences, 2022 Simplex identification via split augmented Lagrangian (SISAL) is a popularly-used algorithm in blind unmixing of hyperspectral images. Developed by José M. Bioucas-Dias in 2009, the algorithm is fundamentally relevant to tackling simplex-structured matrix factorization, and by extension, non-negative matrix factorization, which have many applications ...

Full-spur mapping: refining coral reef carbonate production estimates using underwater photogrammetryFull-spur mapping: refining coral reef carbonate production estimates using underwater photogrammetry [PDF]
Royal Society Open ScienceTraditional methods for estimating calcium carbonate production on coral reefs rely on in-water line transects that sample only a fraction of the reefscape, inherently introducing spatial biases and under-representing the heterogeneity of coral ...
