Python OpenCV cv2.blur()用法及代碼示例


OpenCV-Python是旨在解決計算機視覺問題的Python綁定庫。cv2.blur()方法用於使用歸一化框濾鏡模糊圖像。該函數使用內核將圖像平滑化,表示為:

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

用於以下所有示例的圖像:

範例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) 

輸出:

範例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) 

輸出:
