tf.image.random_flip_left_right

TensorFlow 1 version View source on GitHub

Randomly flip an image horizontally (left to right).

Used in the notebooks

Used in the tutorials

With a 1 in 2 chance, outputs the contents of image flipped along the second dimension, which is width. Otherwise output the image as-is. When passing a batch of images, each image will be randomly flipped independent of other images.

Example usage:

import numpy as np
image = np.array([[[1], [2]], [[3], [4]]])
tf.image.random_flip_left_right(image, 5).numpy().tolist()
[[[2], [1]], [[4], [3]]]

Randomly flip multiple images.

images = np.array(
[
    [[[1], [2]], [[3], [4]]],
    [[[5], [6]], [[7], [8]]]
])
tf.image.random_flip_left_right(images, 6).numpy().tolist()
[[[[2], [1]], [[4], [3]]], [[[5], [6]], [[7], [8]]]]

image 4-D Tensor of shape [batch, height, width, channels] or 3-D Tensor of shape [height, width, channels].
seed A Python integer. Used to create a random seed. See tf.compat.v1.set_random_seed for behavior.

A tensor of the same type and shape as image.

ValueError if the shape of image not supported.
