定义

• cv2.blur(img,size)
• cv2.GaussianBlur(img,size,std)
• cv2.medianBlur(img,size)

用法

示例

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

img = cv2.imread('D:/2.png') 

blur = cv2.blur(img,(5,5)) 
gaussian = cv2.GaussianBlur(img,(5,5),0)
median = cv2.medianBlur(img,5)

cv2.imshow('image',img)
cv2.imshow('blur',blur) 
cv2.imshow('gaussian',gaussian)
cv2.imshow('median',median)

k=cv2.waitKey(1) 
cv2.destroyAllWindows()
