# scipy.signal.medfilt

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

  Perform a median filter on an N-dimensional array.

  Description:

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

  Inputs:

  > in – An N-dimensional input array. kernel_size – 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.

  Outputs: (out,)

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