EX 09 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 pacakages

Step2:

Create the text using cv2.putText

Step3:

Create the structuring element

Step4:

Erode the image

Step5:

Dilate the Image

Program:

Developed by : Sanjay S
Register Number : 212221243002

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_SCRIPT_SIMPLEX
cv2.putText(img ,'Sanjay S',(60,70),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))
cv2.erode(img,kernel)

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.
