Python OpenCV how to save an image after transforming it

Question

I am new to python. I am using opencv to tranform an image.
Below are the two last lines in the script:

warped = warped.astype("uint8") * 255
cv2.imshow("Scanned", imutils.resize(warped, height = 650))

I would like to save the warped image as a jpeg file.
How do I go about it?

Answer 1

首先将修改后的图像保存在变量中，然后使用以下命令：

cv2.imwrite("IMAGE_NAME.png", warpedimage)
