Implementation-of-Erosion-and-Dilation

Aim

To implement Erosion and Dilation using Python and OpenCV.

Software Required

1. Anaconda - Python 3.7
2. OpenCV

Algorithm:

Step 1:

Import the necessary packages.

Step 2:

Create the Text using cv2.putText

Step 3:

Create the structuring element.

Step 4:

Erode the image.

Step 5:

Dilate the image.

Program:

/*
Developed by   : Tamil venthan R S
Register Number: 212220230054
*/

# Import the necessary packages
import cv2
import numpy as np
import matplotlib.pyplot as plt
# Create the Text using cv2.putText
img1=np.zeros((300,500),dtype='uint8')
font=cv2.FONT_ITALIC=3
img2=cv2.putText(img1,"Kumaran",(5,70),font,3,(255),5,cv2.LINE_AA)
cv2.imshow("Original",img2)
cv2.waitKey(0)
cv2.destroyAllWindows()
# Create the structuring element
kernel1=np.ones((5,5),np.uint8)
# Erode the image
erode=cv2.erode(img2,kernel1)
cv2.imshow("Erosion1",erode)
cv2.waitKey(0)
cv2.destroyAllWindows()
# Dilate the image
dilute=cv2.dilate(img2,kernel2)
cv2.imshow("Dilution",dilute)
cv2.waitKey(0)
cv2.destroyAllWindows()

Output:

Display the input Image

Display the Eroded Image

Display the Dilated Image

Result

Thus the generated text image is eroded and dilated using python and OpenCV.
