Descrizione
In arrayfire previously, I've used medfilt1 to apply a median filter to multiple dimensions. However, in the python binding the output from dim1 is copied to all other dims.
For example:
import arrayfire as af
data = af.randn(10, 10)
filt_data = af.medfilt1(data, 3)
filt_data.to_ndarray()
