    Try cv2.filter2D function

    import cv2
import numpy as np 

kernel = np.ones((5,5),np.float32)/25
img = cv2.imread('imagename.extension')
blurred = cv2.filter2D(img, -1, kernel)
cv2.imwrite('blurred_image.extension', blurred)

    According to the description given here of the surface blur filter, you can use bilateral filtering.
    I’m qouting from the above link.

    The Surface Blur filter blurs an image while preserving edges. This
    filter is useful for creating special effects and for removing noise
    and graininess.

    Also check here and here for additional details and this opencv tutorial on filtering.

    In the example below, I’m using the image given in the shellandslate site.

    import cv2 as cv
im = cv.imread('input.png')
blur = cv.bilateralFilter(im,9,75,75)

    Result:

    input
    blur
