In this program, we will perform the closing operation using the cv2.morphologyEx() function. Closing removes small holes in the foreground, changing small holes of background into foreground. This technique can also be used to find specific shapes in an image. The function we will use for this task is cv2.morphologyEx(image, cv2.MORPH_CLOSE, kernel).
Step 1: Import cv2 and numpy. Step 2: Read the image. Step 3: Define the kernel. Step 4: Pass the image and kernel to the cv2.morphologyex() function. Step 4: Display the output.
import cv2 import numpy as np image = cv2.imread('testimage.jpg') kernel = np.ones((5,5), np.uint8) image = cv2.morphologyEx(image, cv2.MORPH_CLOSE, kernel) cv2.imshow('Closing', image)
