Flip Image OpenCV Project

To flip the image both vertically and horizontally, i.e. along both the x and y axis, we need to provide a negative value to flipCode.
OpenCV-Python is a library of programming functions mainly aimed at real-time computer vision. cv2.flip() method is used to flip a 2D array. The function cv::flip flips a 2D array around vertical, horizontal, or both axes. The OpenCV function that flips the image (= ndarray ) vertically and horizontally is cv2. flip()
The image is flipped according to the value of flipCode as follows:
flipcode = 0 : flip vertically.
flipcode > 0 : flip horizontally.
flipcode < 0 : flip vertically and horizontally
