mne_nirs.signal_enhancement.enhance_negative_correlation#
- mne_nirs.signal_enhancement.enhance_negative_correlation(raw)[source]#
Apply negative correlation enhancement algorithm.
As described in [1]. This function will return a modified raw instance that has the enhancement applied to it. This function can only be run on data containing hbo and hbr types.
- Parameters:
- rawinstance of Raw
Haemoglobin data.
- Returns:
- rawinstance of Raw
The modified raw instance.
