To implement Opening and Closing using Python and OpenCV.
- Anaconda - Python 3.7
- OpenCV
Import the necessary packages.
Create the Text using cv2.putText.
Create the structuring element.
Use Opening operation.
Use Closing Operation.
Print the output and end the program.

plt.imshow(text_image,'magma')
plt.axis('off')kernel = cv2.getStructuringElement(cv2.MORPH_CROSS,(7,7))opening_image = cv2.morphologyEx(text_image,cv2.MORPH_OPEN,kernel)
plt.title("Opening")
plt.imshow(opening_image,'magma')
plt.axis('off')closing_image = cv2.morphologyEx(text_image,cv2.MORPH_CLOSE,kernel)
plt.title("Closing")
plt.imshow(closing_image,'magma')
plt.axis('off')
Thus the Opening and Closing operation is used in the image using python and OpenCV.
