OpenCV与PIL.Image图片格式互转

OpenCV转换成PIL.Image格式：

import cv2    
from PIL import Image    
import numpy    
    
img = cv2.imread("a.jpg")    
cv2.imshow("a",img)    
image = Image.fromarray(cv2.cvtColor(img,cv2.COLOR_BGR2RGB))    
image.show()    
cv2.waitKey()   

PIL.Image转换成OpenCV格式：

import cv2    
from PIL import Image    
import numpy    
    
image = Image.open("a.jpg")    
image.show()    
img = cv2.cvtColor(numpy.asarray(image),cv2.COLOR_RGB2BGR)    
cv2.imshow("a", img)    
cv2.waitKey()
