Sparse Space-Time Deconvolution for Calcium Image Analysis
Ferran Diego Andilla · Fred Hamprecht
Tue Dec 09 12:30 PM -- 12:50 PM (PST) @ Level 2, room 210
We describe a unified formulation and algorithm to find an extremely sparse representation for Calcium image sequences in terms of cell locations, cell shapes, spike timings and impulse responses. Solution of a single optimization problem yields cell segmentations and activity estimates that are on par with the state of the art, without the need for heuristic pre- or postprocessing. Experiments on real and synthetic data demonstrate the viability of the proposed method.
