Python OpenCV cv2.blur()用法及代码示例

OpenCV-Python是旨在解决计算机视觉问题的Python绑定库。cv2.blur()方法用于使用归一化框滤镜模糊图像。该函数使用内核将图像平滑化，表示为：

用法： cv2.blur(src, ksize[, dst[, anchor[, borderType]]])

参数:

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

返回值: It returns an image.

用于以下所有示例的图像：

范例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：

范例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：
