如何使用cv2.FileStorage

Question

我曾經使用opencv C++的FileStorage類，它非常有用，但我找不到如何在opencv python中使用它。請幫幫我。感謝

Answer 1

`import cv2 
import numpy as np 
f = cv2.FileStorage('test.yml',flags=1) 
a = np.zeros((10,10),dtype=np.uint8) 
f.write(name='matrix',value=a) 
f.release() 
` 

結果是在 'test.yml' '

%YAML:1.0
