Python PIL | MinFilter() and MaxFilter() method

PIL is the Python Imaging Library which provides the python interpreter with image editing capabilities. The ImageFilter module contains definitions for a pre-defined set of filters, which can be used with the Image.filter() method.

PIL.ImageFilter.MinFilter() method creates a min filter. Picks the lowest pixel value in a window with the given size.

Syntax: PIL.ImageFilter.MinFilter(size=3)

Parameters: 
size: The kernel size, in pixels.

Image used:

# Importing Image and ImageFilter module from PIL package
from PIL import Image, ImageFilter

# creating a image object
im1 = Image.open(r"C:\Users\sadow984\Desktop\download2.JPG")

# applying the min filter
im2 = im1.filter(ImageFilter.MinFilter(size = 3))

im2.show()

Output:

PIL.ImageFilter.MinFilter() method creates a max filter. Picks the largest pixel value in a window with the given size.

Syntax: PIL.ImageFilter.MaxFilter(size=3)

Parameters:
