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

Step6:

Display the output images

Program:

Import the necessary packages

import cv2
import numpy as np 
import matplotlib.pyplot as plt

Create the Text using cv2.putText

img1=np.zeros((100,400),dtype='uint8')
font=cv2.FONT_HERSHEY_SIMPLEX
cv2.putText(img1,'Abinaya',(5,70),font,2,(255),5,cv2.LINE_AA)

Create the structuring element

kernel=np.ones((5,5),np.uint8)
kernel1=cv2.getStructuringElement(cv2.MORPH_CROSS,(7,7))

Erode the image

image_erode1=cv2.erode(img1,kernel1)
plt.imshow(image_erode1)
plt.axis("off")

Dilate the image

image_dilate1=cv2.dilate(img1,kernel1)
plt.imshow(image_dilate1)
plt.axis("off")

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.
