In this program, we will calculate the variance of all the pixels in each channel using the Pillow library. There are a total three channels in an image and therefore, we will get a list of three values.
Step 1: Import the Image and ImageStat libraries. Step 2: Open the image. Step 3: Pass the image to the stat function of the imagestat class. Step 4: Print the variance of the pixels.
from PIL import Image, ImageStat im = Image.open('image_test.jpg') stat = ImageStat.Stat(im) print(stat.var)
