cv3.transform.vflip

cv3.transform.vflip(img)[source]

Flip image vertically (around x-axis).

Parameters:: img (numpy.ndarray) – Input image.
Returns:: Vertically flipped image.
Return type:: numpy.ndarray

Example

>>> import cv3
>>> import numpy as np
>>> # Create a simple image
>>> img = np.zeros((100, 100, 3), dtype=np.uint8)
>>> img[25:75, 25:75] = [255, 255, 255]  # White square
>>> # Flip vertically
>>> flipped = cv3.vflip(img)
