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 using cv2.erode().

Program:

#DEVELOPED BY : M LOKESH KRISHNAA 
#REG.NO : 212220230030
import numpy as np
import cv2
import matplotlib.pyplot as plt
img1=np.zeros((100,500),dtype='uint8')
font=cv2.FONT_HERSHEY_COMPLEX_SMALL
# Create the Text using cv2.putText
cv2.putText(img1,'LOKESH KRISHNAA',(5,70),font,2,(255),5,cv2.LINE_AA)
plt.imshow(img1,cmap='gray')
kernel1=cv2.getStructuringElement(cv2.MORPH_CROSS,(7,7))
img_erode=cv2.erode(img1,kernel1)
plt.imshow(img_erode,cmap='gray')
img_dilate=cv2.dilate(img1,kernel1)
plt.imshow(img_dilate,cmap='gray')

Output:

Display the input Image

1

Display the Eroded Image

2

Display the Dilated Image

3

Result

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