scipy.signal.medfilt2d

scipy.signal.medfilt2d(input, kernel_size=3)

Median filter a 2-dimensional array.

Apply a median filter to the input array using a local window-size given by kernel_size (must be odd).

Parameters :

input : array_like

A 2-dimensional input array.

kernel_size : array_like, optional

A scalar or a list of length 2, 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 is a kernel of size (3, 3).

Returns :

out : ndarray

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