The adaptive_sharpen() function is an inbuilt function in the Python Wand ImageMagick library which is used to sharpens the image. The intensity is less far from the edges. It is present in class wand.image.
Syntax:
adaptive_sharpen(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
from wand.image import Image
with Image(filename = '../geeksforgeeks.png' ) as image:
with image.clone() as adaptive_sharpen:
adaptive_sharpen.adaptive_sharpen( 0 , 3 , 'Green' )
adaptive_sharpen.save(filename = 'adaptive_sharpen1.jpg' )
|
Output:
Example 2:
Python3
from wand.image import Image
from wand.drawing import Drawing
from wand.color import Color
with Drawing() as draw:
draw.stroke_color = Color( 'black' )
draw.stroke_width = 1
draw.fill_color = Color( 'white' )
draw.circle(( 200 , 200 ),
( 100 , 100 ))
draw.font = '../Helvetica.ttf'
draw.font_size = 30
with Image(width = 400 , height = 400 , background = Color( '# 45ff33' )) as pic:
draw.text( int (pic.width / 3 ), int (pic.height / 2 ), 'GeeksForGeeks !' )
draw(pic)
pic.adaptive_sharpen( 8 , 2 , 'Red' )
pic.save(filename = 'adaptive_sharpen2.jpg' )
