Fitting a linescan image. **A**  Each time trace in the raw fluorescence signal(A)  is fitted and a denoised image is obtained (B).The obtained. **B** The  denoised image is a sum of fitted events (C) events(**C**)  and baseline (D). baseline(**D**).  ΔF/F0 image (E) image(**E**)  is obtained by dividing the event image (C) image(**C**)  with the baseline (D). baseline(**D**).  Because the fitted baseline is a function of time, the \(\Delta F/F_0\) image is automatically corrected for temporal changes in background flourescence (e.g., bleaching). (F) **F**  The residual signal obtained when subtracting the fitted image from raw data. **G**  Residual values are normally distributed (G). distributed.
