Opening--Closing

Aim

To implement Opening and Closing using Python and OpenCV.

Software Required

  1. Anaconda - Python 3.7
  2. OpenCV

Algorithm:

Step1:

Import the necessary packages.

Step2:

Create the Text using cv2.putText.

Step3:

Create the structuring element

Step4:

Use Opening operation

Step5:

Use Closing Operation

Program:

Name:Swathika G

Reg No:212221230113

# Import the necessary packages
import numpy as np
import cv2
import matplotlib.pyplot as plt
# Load the Image
img1=np.zeros((100,600),dtype='uint8')
font=cv2.FONT_HERSHEY_COMPLEX_SMALL
# Create the Text using cv2.putText
cv2.putText(img1,' GRAND THEFT AUTO ',(5,70),font,2,(255),5,cv2.LINE_AA)
plt.imshow(img1,cmap='gray')
plt.title('Input Text'), plt.xticks([]), plt.yticks([])
plt.show()
# Create the structuring element
kernel1=cv2.getStructuringElement(cv2.MORPH_CROSS,(7,7))
# Use Opening operation
image1=cv2.morphologyEx(im,cv2.MORPH_OPEN,kernel1)
plt.imshow(image1,cmap='gray')
plt.title('OPENING'), plt.xticks([]), plt.yticks([])
plt.show()
# Use Closing Operation
image1=cv2.morphologyEx(im,cv2.MORPH_CLOSE,kernel1)
plt.imshow(image1,cmap='gray')
plt.title('CLOSING'), plt.xticks([]), plt.yticks([])
plt.show()

Output:

Display the input Image

OUTPUT





Display the result of Opening

OUTPUT





Display the result of Closing

OUTPUT





Result

Thus the Opening and Closing operation is used in the image using python and OpenCV.
