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.
Syntax: cv2.cv.flip(src, flipCode[, dst] )
Parameters: src: Input array.
dst: Output array of the same size and type as src.
flip code: A flag to specify how to flip the array; 0 means flipping around the x-axis and positive value (for example, 1) means flipping around y-axis. Negative value (for example, -1) means flipping around both axes. Return Value: It returns an image.
Image used for all the below examples:
Example:
Python3
# Python program to explain cv2.flip() method # importing cv2import cv2 # pathpath = r'C:\Users\user\Desktop\Lazyroar14.png' # Reading an image in default modesrc = cv2.imread(path) # Window name in which image is displayedwindow_name = 'Image' # Using cv2.flip() method# Use Flip code 0 to flip verticallyimage = cv2.flip(src, 0) # Displaying the imagecv2.imshow(window_name, image)cv2.waitKey(0) |
Output:
Flipped Vertically
