Example :
Syntax :
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.
Example #1:
Input Image –
# 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 –
# 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) |
