Fast online deconvolution of calcium imaging data

Thresholding can improve the accuracy of spike inference.
(A) Inferred trace using L1 penalty (L1, blue) and the thresholded OASIS (Thresh., green). The data (gray) are simulated with AR(1) model. (B) Inferred spiking activity. (C) The detected events using thresholded OASIS depend on the selection of smin. The ground truth is shown in red. (D,E,F), same as (A,B,C), but the data are simulated with AR(2).
