refine_signal_mask

mufasa.signals.refine_signal_mask(sig_mask, minsize=2, expand=20, clean=True)

Refine a signal mask by removing noisy features and expanding the mask.

Parameters:

• sig_mask (LazyComparisonMask or ndarray) – Initial signal mask.

• minsize (int, optional) – Minimum number of continuous spectral channels for signal mask.

• expand (int, optional) – Number of spectral channels to expand signal regions.

• clean (bool, optional) – Remove spatially isolated pixels.

Returns:

Refined signal mask.

Return type:

ndarray
