TensorFlow provides tf.io and tf.image modules for reading and processing the images. Below is the code snippet for reading and processing images with tf.io and tf.image . RUn the code snippet in Jupyter or Colab notebook.

  • Download the sample image by clicking here and keep it in working directory with name flower.jpg
  • Import modules and read image from file
    • 
import tensorflow as tf
import matplotlib.pyplot as plt

image=tf.io.read_file("flower.jpg")
image = tf.io.decode_jpeg(image)
  • Print original image
    • 
plt.figure()
plt.imshow(image)
    flower
  • Flipping image left to right with tf.image 
    • 
image = tf.image.flip_left_right(image)
plt.figure()
plt.imshow(image)
    flower
  • Flipping image upside down with tf.image
    • 
image = tf.image.flip_up_down(image)
plt.figure()
plt.imshow(image)
    flower
  • Adjusting brightness of image with tf.image
    • 
image = tf.image.adjust_brightness(image, delta=0.5)
plt.figure()
plt.imshow(image)
    flower
