Localized semi-nonnegative matrix factorization (LocaNMF) of widefield calcium imaging data
Fig 2
LocaNMF can accurately recover the spatial and temporal components in simulated WFCI data.
(A) Left column: two example ground truth spatial components; Middle and Right columns: the corresponding spatial components as recovered by (Middle column) LocaNMF; (Right column) SVD. (B) Correlation between ground truth spatial components and those recovered by (Top) LocaNMF; (Bottom) SVD.
