How to gauss-filter (blur) a floating point numpy array

Question

I have got a numpy array a of type float64. How can I blur this data with a Gauss filter?

I have tried

from PIL import Image,          


        

Answer 1

If you have a two-dimensional numpy array a, you can use a Gaussian filter on it directly without using Pillow to convert it to an image first. scipy has a function gaussian_filter that does the same.

from scipy.ndimage.filters import gaussian_filter

blurred = gaussian_filter(a, sigma=7)
