Python – Wand 中的自适应模糊

自适应模糊是一种模糊。唯一的区别是图像中可检测边缘周围的模糊强度较小，而在没有边缘的区域则较大。自适应模糊可以使用adaptive_blur函数来完成。

Syntax : 
 

Python3

# import Image from wand.image module
from wand.image import Image
 
# read file using Image function
with Image(filename ="koala.jpeg") as img:
 
    # perform adaptive blur effect using adaptive_blur() function
    img.blur(radius = 8, sigma = 3)
 
    # save final image
    img.save(filename ="adblur_koala.jpeg")

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.

示例 #1：

Python3

wand.image.adaptive_blur(radius="radius_value",
                           sigma="sigma_value",
            channel = "optional_channel_value")
 
# radius should always be greater than sigma(standard deviation)

输出：

示例 #2：

Python3

# import Image from wand.image module
from wand.image import Image
 
# read file using Image function
with Image(filename ="gfg.png") as img:
    # perform adaptive blur effect using adaptive_blur() function
    img.adaptive_blur(radius = 8, sigma = 4)
    # save final image
    img.save(filename ="adblur_gfg.png")

输出：
