skimage2.filters.wiener(data, impulse_response=None, filter_params=None, K=0.25, predefined_filter=None)

Minimum Mean Square Error (Wiener) inverse filter.

Parameters:

datandarray of shape (M, N)

Input data.

Kfloat or ndarray of shape (M, N)

Ratio between power spectrum of noise and undegraded image.

impulse_responsecallable f(r, c, **filter_params)

Impulse response of the filter. See LPIFilter2D.__init__.

filter_paramsdict, optional

Additional keyword parameters to the impulse_response function.

Other Parameters:

predefined_filterLPIFilter2D

If you need to apply the same filter multiple times over different images, construct the LPIFilter2D and specify it here.
