Wand adaptive_blur() function – Python

The adaptive_blur() function is an inbuilt function in the Python Wand ImageMagick library which is used to blur the image by decrementing the Gaussian value as the operator. It is present in class wand.image.

Syntax:

adaptive_blur(radius, sigma, channel)

Parameters: This function accepts three parameters as mentioned above and defined below: 

• radius: This parameter is used to specify the value of radius which is the size of the gaussian aperture.
• sigma: This parameter is used to specify the value of sigma which is the standard deviation of the gaussian filter.
• channel: This parameter is used to specify the value of image channel as undefined, ‘red’, ‘gray’, ‘cyan’, ‘green’, ‘magenta’, ‘blue’, ‘yellow’, ‘alpha’, ‘opacity’, ‘black’, ‘index’, ‘composite_channels’, ‘all_channels, ‘sync_channels’, ‘default_channels’.

Return Value: This function returns the Wand ImageMagick object.

Example 1:

Python3

# 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')

Output:

Example 2:

Python3

# 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')

Output:
