问题：

##边界填充
import cv2
top_size,bottom_size,left_size,right_size=(50,50,50,50)
replicate=cv2.copyMakeBorder(img,top_size,bottom_size,left_size,right_size,boderType=cv2.BORDER_REPLICATE)
reflect=cv2.copyMakeBorder(img,top_size,bottom_size,left_size,right_size,boderType=cv2.BORDER_REFLECT)
reflect101=cv2.copyMakeBorder(img,top_size,bottom_size,left_size,right_size,boderType=cv2.BORDER_REFLECT101)
wrap=cv2.copyMakeBorder(img,top_size,bottom_size,left_size,right_size,boderType=cv2.BORDER_WRAP)
constant=cv2.copyMakeBorder(img,top_size,bottom_size,left_size,right_size,boderType=cv2.BORDER_CONSTANT,value=0) 
输出结果：
error Traceback (most recent call last)
<ipython-input-39-820a457b4770> in <module>
      2 import cv2
      3 top_size,bottom_size,left_size,right_size=(50,50,50,50)
----> 4 replicate=cv2.copyMakeBorder(img,top_size,bottom_size,left_size,right_size,boderType=cv2.BORDER_REPLICATE)
      5 reflect=cv2.copyMakeBorder(img,top_size,bottom_size,left_size,right_size,boderType=cv2.BORDER_REFLECT)
      6 reflect101=cv2.copyMakeBorder(img,top_size,bottom_size,left_size,right_size,boderType=cv2.BORDER_REFLECT101)

error: OpenCV(4.5.2) :-1: error: (-5:Bad argument) in function 'copyMakeBorder'
> Overload resolution failed:

分析：

error: OpenCV(4.5.2) :-1: error: (-5:Bad argument) in function 'copyMakeBorder'
> Overload resolution failed:
>  - copyMakeBorder() missing required argument 'borderType' (pos 6)
>  - copyMakeBorder() missing required argument 'borderType' (pos 6)

"borderType"拼写错误！！！！

正确代码：

##边界填充
import cv2
top_size,bottom_size,left_size,right_size=(50,50,50,50)
replicate=cv2.copyMakeBorder(img,top_size,bottom_size,left_size,right_size,borderType=cv2.BORDER_REPLICATE)
reflect=cv2.copyMakeBorder(img,top_size,bottom_size,left_size,right_size,borderType=cv2.BORDER_REFLECT)
reflect101=cv2.copyMakeBorder(img,top_size,bottom_size,left_size,right_size,borderType=cv2.BORDER_REFLECT101)
wrap=cv2.copyMakeBorder(img,top_size,bottom_size,left_size,right_size,borderType=cv2.BORDER_WRAP)
constant=cv2.copyMakeBorder(img,top_size,bottom_size,left_size,right_size,borderType=cv2.BORDER_CONSTANT,value=0) 


import matplotlib.pyplot as plt
plt.subplot(231),plt.imshow(img,'gray'),plt.title('ORIGINAL')
plt.subplot(232),plt.imshow(replicate,'gray'),plt.title('REPLICATE')
plt.subplot(233),plt.imshow(reflect,'gray'),plt.title('REFLECT')
plt.subplot(234),plt.imshow(reflect101,'gray'),plt.title('REFLECT101')
plt.subplot(235),plt.imshow(wrap,'gray'),plt.title('WRAP')
plt.subplot(236),plt.imshow(constant,'gray'),plt.title('CONSTANTL')

plt.show()
