Reduce Image Noise Using cv2.fastNlMeansDenoisingColored() in Python OpenCV

In this tutorial, we will use an example to introduce you how to use cv2.fastNlMeansDenoisingColored() to reduce noise from an image.

1.Read an image

import cv2
img = cv2.imread("pyn1.png")

2.Reduce image noise

result = cv2.fastNlMeansDenoisingColored(img,None,20,10,7,21)

3.Display result

cv2.imshow("Original Image", img)
cv2.imshow("Denoised Image", result)
cv2.waitKey(0)
