For each row of the ICA-source matrix the implementation scores the component against the EOG reference (maximum absolute Pearson correlation across EOG channels), against the ECG reference (same statistic across ECG channels) and against a muscle spectral heuristic (fraction of total power above 30 Hz estimated from a Hamming-windowed periodogram); whichever score first crosses its threshold determines the assigned IcaComponentLabel, otherwise the component is labelled Brain. Components labelled Eog, Ecg or Muscle are reported by MlIcaLabel::findArtifactComponents in the order required by the ICA reconstruction code so the calling pipeline can pass them straight through apply / exclude.
