Median window
An implementation and extention of Mark S. Friedrichs' model-free algorithm
baseline.medianWindow(spectra, hwm, hws, end)
spectra |
Matrix with spectra in rows |
hwm |
Window half width for local medians |
hws |
Window half width for local smoothing (optional) |
end |
Original endpoint handling (optional boolean) |
An algorithm finding medians in local windows and smoothing with gaussian weighting
baseline |
Matrix of baselines corresponding to spectra |
corrected |
Matrix of baseline corrected spectra |
