scipy.signal.medfilt(volume, kernel_size=None)

Perform a median filter on an N-dimensional array.

Apply a median filter to the input array using a local window-size given by kernel_size.

Parameters :

volume : array_like

An N-dimensional input array.

kernel_size : array_like, optional

A scalar or an N-length list giving the size of the median filter window in each dimension. Elements of kernel_size should be odd. If kernel_size is a scalar, then this scalar is used as the size in each dimension. Default size is 3 for each dimension.

Returns :

out : ndarray

An array the same size as input containing the median filtered result.
