Web1 Sep 2024 · The ndimage routines uniform_filter and uniform_filter1d both expand NaNs out to the far edge of the original data, regardless of the size of the filter being used. I expected uniform_filter to behave similarly to convolve with a uniform kernel of the same size - namely that anywhere the kernel touches a NaN the result is also a NaN. However, … Webweights = np.ones (window_size) / window_size. # Compute the convolution between the signal and the filter. mean_values = np.convolve (arr, weights, mode='valid') # Compute the edge values. left_edge, right_edge = movmean_edge_cases (arr, window_size) # add edge values to the original list.
