Wand - blur() function in Python

Last Updated : 22 Apr, 2020

Blurring Image means making an image fuzzy or hazy. A blur image is indefinite and it is unable to see an image clearly. Blur is of many types, like - Adaptive blur, Gaussian blur, Selective Blur etc. In order to blur an image we use blur() function. blur() function takes three arguments. Example :

Syntax : Python3 wand.image.blur(radius="radius_value", sigma="sigma_value", channel = "optional_channel_value") Parameters :

Parameter Input Type Description

radius numbers.real the radius of the, in pixels, not counting the center pixel. Default is 0.0.

sigma numbers.real the standard deviation of the, in pixels. Default value is 0.0.

channel basestring Optional color channel to apply blur.

Parameter	Input Type	Description
radius	numbers.real	the radius of the, in pixels, not counting the center pixel. Default is 0.0.
sigma	numbers.real	the standard deviation of the, in pixels. Default value is 0.0.
channel	basestring	Optional color channel to apply blur.

Example #1: Input Image -

Python3 1==

# import Image from wand.image module
from wand.image import Image

# read file using Image function
with Image(filename ="koala.jpeg") as img:

    # perform blur effect using blur() function
    img.blur(radius = 0, sigma = 3)

    # save final image
    img.save(filename ="blur_koala.jpeg")

Output:

Example #2: Input Image -

Python3 1==

# import Image from wand.image module
from wand.image import Image
from wand.display import display

# read file using Image function
with Image(filename ="human1.jpeg") as img:

    # perform blur effect using blur() function
    img.blur(radius = 3, sigma = 4, )

    # save final image
    img.save(filename ="blurhuman.jpeg")
    display(img)

Output:
