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:

Step1:

Import the necessary packages.

Step2:

Create the Text using cv2.putText.

Step3:

Create the structuring element.

Step4:

Erode and Dilate the image.

Step5:

End Program.




Program:

# Developed By   : Aishree Ramesh
# Register Number: 212220230003

# Import the necessary packages
import cv2
import numpy as np
import matplotlib.pyplot as plt

# Create the Text using cv2.putText
img1 = np.zeros((100,270), dtype = 'uint8')
font = cv2.FONT_HERSHEY_SIMPLEX
cv2.putText(img1,'Aishree',(5,70), font, 2,(255),5,cv2.LINE_AA)
plt.imshow(img1,'gray')

# Create the structuring element
cv2.erode(img1, kernel)
kernel = cv2.getStructuringElement(cv2.MORPH_CROSS,(7,7))

# Erode the image
image_erode1 = cv2.erode(img1,kernel)
plt.imshow(image_erode1, 'gray')

# Dilate the image
image_dilate1 = cv2.dilate(img1, kernel)
plt.imshow(image_dilate1, 'gray')

Output:

Display the input Image

image

Display the Eroded Image

image

Display the Dilated Image

image

Result

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