Python讲堂　PIL.Image和OpenCV图像格式相互转换

PIL.Image转换成OpenCV格式：

import cv2




from PIL import Image




import numpy



 



image = Image.open("plane.jpg")



image.show()



img = cv2.cvtColor(numpy.asarray(image),cv2.COLOR_RGB2BGR)



cv2.imshow("OpenCV",img)



cv2.waitKey()

OpenCV转换成PIL.Image格式：

import cv2




from PIL import Image




import numpy



 



img = cv2.imread("plane.jpg")



cv2.imshow("OpenCV",img)



image = Image.fromarray(cv2.cvtColor(img,cv2.COLOR_BGR2RGB))



image.show()



cv2.waitKey()

判断图像数据是否是OpenCV格式：

isinstance(img, np.ndarray)
