You can blur an image in OpenCV Python by any of the given methods. I highly recommend you get the “Computer Vision: Models, Learning, and Inference Book” to learn Computer Vision.
Method 1: Averaging
import cv2
img = cv2.imread('baby.jpg')
Simple_blur = cv2.blur(img,(10,10))
cv2.imshow("Original Image",img)
cv2.imshow('Simple blurring',Simple_blur)
cv2.waitKey(0)
cv2.destroyAllWindows()
Method 2: Gaussian Blurring
import cv2
img = cv2.imread('baby.jpg')
gaussian_Blur = cv2.GaussianBlur(img, (5,5),0)
cv2.imshow("Original Image",img)
cv2.imshow('Gaussian Blurring', gaussian_Blur)
cv2.waitKey(0)
cv2.destroyAllWindows()
Method 3: Median Blurring
import cv2
img = cv2.imread('baby.jpg')
median_Blur = cv2.medianBlur(img,5)
cv2.imshow("Original Image",img)
cv2.imshow('Median Blurring', median_Blur)
cv2.waitKey(0)
cv2.destroyAllWindows()
Method 4: Bilateral Filtering
import cv2
img = cv2.imread('baby.jpg')
bilateral_Filter = cv2.bilateralFilter(img,9,75,75)
cv2.imshow("Original Image",img)
cv2.imshow('Bilateral Filtering', bilateral_Filter)
cv2.waitKey(0)
cv2.destroyAllWindows()
