ramanspy.preprocessing.despike.WhitakerHayes

class ramanspy.preprocessing.despike.WhitakerHayes(*, kernel_size: int = 3, threshold: Number = 8)[source]

Cosmic rays removal based on modified z-scores filtering.

Parameters:

  • kernel_size (int, optional, default=3) – The size of the kernel to use for the algoritm.

  • threshold (Number, optional, default=8) – The modified z_score threshold to use to identify spikes.
