Static Methods

compute(List<List<double>> spectra) List<double>
Computes the spectral flux for a list of spectra, returning a list of flux values where the first value is 0 (since there is no previous spectrum to compare to).
positiveDifference(List<double> current, List<double> previous) double
Computes the positive difference between two spectra, summing only the positive changes in magnitude across all frequency bins.
