Python OpenCV | cv2.blur() 方法

OpenCV-Python是一个Python绑定库，旨在解决计算机视觉问题。 cv2.blur()方法用于使用归一化框过滤器模糊图像。该函数使用表示为的内核平滑图像：

Syntax: cv2.blur(src, ksize[, dst[, anchor[, borderType]]])
Parameters:
src: It is the image whose is to be blurred.
ksize: A tuple representing the blurring kernel size.
dst: It is the output image of the same size and type as src.
anchor: It is a variable of type integer representing anchor point and it’s default value Point is (-1, -1) which means that the anchor is at the kernel center.
borderType: It depicts what kind of border to be added. It is defined by flags like cv2.BORDER_CONSTANT, cv2.BORDER_REFLECT, etc
Return Value: It returns an image.

用于以下所有示例的图像：

示例 #1：

# Python program to explain cv2.blur() method 
  
# importing cv2 
import cv2 
  
# path 
path = r'C:\Users\Rajnish\Desktop\geeksforgeeks\geeks.png'
  
# Reading an image in default mode 
image = cv2.imread(path) 
  
# Window name in which image is displayed 
window_name = 'Image'
  
# ksize
ksize = (10, 10)
  
# Using cv2.blur() method 
image = cv2.blur(image, ksize) 
  
# Displaying the image 
cv2.imshow(window_name, image) 

输出：

示例 #2：

# Python program to explain cv2.blur() method 
  
# importing cv2 
import cv2 
  
# path 
path = r'C:\Users\Rajnish\Desktop\geeksforgeeks\geeks.png'
  
# Reading an image in default mode 
image = cv2.imread(path) 
  
# Window name in which image is displayed 
window_name = 'Image'
  
# ksize
ksize = (30, 30)
  
# Using cv2.blur() method 
image = cv2.blur(image, ksize, cv2.BORDER_DEFAULT) 
  
# Displaying the image 
cv2.imshow(window_name, image) 

输出：
