`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.
