ROI 怎样才能转成一张图片？

[tony2278]

s1 = cv2.imread(image_path, 0)
y1 = 0
x1 = 0
print(s1.shape)
height, width = s1.shape
cropImg1 = s1[int(y1):int(y1 + height), int(x1):int(x1 + width)]


请问cropImg1 怎样才能使用 imwrite() 保存成图像？cropImg2 怎样才能转成一张图片？谢谢

region = s2.crop(x2, y2, x2 + height, y2 + width) ？ cv2.imwrite('book-jz.jpg', region)

cv2.imread() ---- Image.open() 互转
