scipy.signal.medfilt2d¶
- scipy.signal.medfilt2d(input, kernel_size=3)[source]¶
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.
