Thresholding functions
======================
The :mod:`~pywt.thresholding` helper module implements the most popular signal
thresholding functions.
Thresholding
------------
.. autofunction:: threshold
.. autofunction:: threshold_firm
The left panel of the figure below illustrates that non-negative Garotte
thresholding is intermediate between soft and hard thresholding. Firm
thresholding transitions between soft and hard thresholding behavior. It
requires a pair of threshold values that define the width of the transition
region.
