adaptive_blur()函数是Python Wand ImageMagick库中的内置函数,该函数用于通过减小高斯值作为运算符来模糊图像。它存在于wand.image类中。
用法:
adaptive_blur(radius, sigma, channel)
参数:该函数接受上面提到的和下面定义的三个参数:
- radius:此参数用于指定半径值,即高斯光圈的大小。
- sigma:此参数用于指定sigma的值,它是高斯滤波器的标准偏差。
- channel:此参数用于将图像通道的值指定为未定义的‘red’, ‘gray’,‘cyan’, ‘green’,‘magenta’, ‘blue’,‘yellow’, ‘alpha’,‘opacity’, ‘black’,‘index’, ‘composite_channels’,‘all_channels,‘sync_channels’, ‘default_channels’。
返回值:此函数返回Wand ImageMagick对象。

范例1:
# Import library from Image
from wand.image import Image
# Import the image
with Image(filename ='../geeksforgeeks.png') as image:
# Clone the image in order to process
with image.clone() as adaptive_blur:
# Invoke adaptive_blur function with radius as 2, sigma as
# 3 and channel as Green
adaptive_blur.adaptive_blur(0, 3, 'Green')
# Save the image
adaptive_blur.save(filename ='adaptive_blur1.jpg')
输出:
范例2:
# Import library from Image
from wand.image import Image
# Import the image
with Image(filename ='../geeksforgeeks.png') as image:
# Clone the image in order to process
with image.clone() as adaptive_blur:
# Invoke adaptive_blur function with radius as 2, sigma as
# 3 and channel as Green
adaptive_blur.adaptive_blur(int(0), int(3), 'Green')
# Save the image
adaptive_blur.save(filename ='adaptive_blur1.jpg')
输出:
