Calculate the area of an image using Matplotlib

Last Updated : 31 Jul, 2021

Let us see how to calculate the area of an image in Python using Matplotlib.

Algorithm:

Import the matplotlib.pyplot module.
Import an image using the imread() method.
Use the shape attribute of the image to get the height and width of the image. It fetches the number of channels in the image.
Calculate the area as, area = height * width.
Display the area.

Example 1: Consider the following image :

“GFG.jpg”

Python3

# import necessary library
import matplotlib.pyplot as plt
 
# read an image
img = plt.imread("GFG.jpg")
 
# fetch the height and width
height, width, _ = img.shape
 
# area is calculated as “height x width”
area = height * width
 
# display the area
print("Area of the image is : ", area)

Output :

Area of the image is : 50244

Example 2: Consider the following image :

“image.jpg”

Python3

# import necessary library
import matplotlib.pyplot as plt
 
# read an image
img = plt.imread("image.jpg")
 
# fetch the height and width
height, width, _ = img.shape
 
# area is calculated as “height x width”
area = height * width
 
# display the area
print("Area of the image is : ", area)
