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 the image

Step5:

Dilate the Image

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


# Create the Text using cv2.putText
img = np.zeros((100,400),dtype='uint8')
font = cv2.FONT_HERSHEY_SIMPLEX
cv2.putText(img,'VENKATA RATHNAM',(40,70),font,2,(255),5,cv2.LINE_AA)
plt.imshow(img)
plt.axis('off')


# Create the structuring element
kernel = np.ones((5,5),np.uint8)
kernel1 = cv2.getStructuringElement(cv2.MORPH_CROSS,(5,5))

# Erode the image
img_erode = cv2.erode(img,kernel1)
plt.imshow(img_erode)
plt.axis('off')

# Dilate the image
img_dilate = cv2.dilate(img,kernel1)
plt.imshow(img_dilate)
plt.axis('off')

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.
