pyacs.gts.lib.filters.total_variation module¶
Total variation filters from https://github.com/albarji/proxTV Total variation filters are useful to preserve edges in a signal (edge filter).
-
pyacs.gts.lib.filters.total_variation.edge(self, lbda, in_place=False, verbose=True)[source]¶ Edge Gts filter using a L1 total variation filter. The signal is assumed to be piecewise constant.
- Parameters
lbda – lambda parameter
in_place – if True then replace the current time series
verbose – boolean, verbose mode
- Returns
the filtered time series

pyacs.gts.lib.filters.total_variation.edge_l2(self, lbda, in_place=False, verbose=True)[source]¶ Gts filter using a L2 total variation filter. The signal is assumed to be detrended.
- Parameters
lbda – lambda parameter
in_place – if True then replace the current time series
verbose – boolean, verbose mode
- Returns
the filtered time series
