Smoothing images – OpenCV 3.4 with python 3 Tutorial 16
[python]
import cv2
import numpy as np
img = cv2.imread("early_1800.jpg")
averaging = cv2.blur(img, (21, 21))
gaussian = cv2.GaussianBlur(img, (21, 21), 0)
median = cv2.medianBlur(img, 5)
bilateral = cv2.bilateralFilter(img, 9, 350, 350)
cv2.imshow("Original image", img)
cv2.imshow("Averaging", averaging)
cv2.imshow("Gaussian", gaussian)
cv2.imshow("Median", median)
cv2.imshow("Bilateral", bilateral)
cv2.waitKey(0)
cv2.destroyAllWindows()
