Recipe Objective

How to change brightness of a image using tf?

This is achieved by using "tf.image.adjust_brightness" function available tensorflow. This function will adjust the brightness of the RGB or the grayscale images. This method is a convenience method which converts the RGB images to float representation, adjust the brightness and then converts them back into the original data type.

Step 1 - Import library

import tensorflow as tf

Step 2 - Take a Sample image

path_image = "/content/yellow-orange-starburst-flower-nature-jpg-192959431.jpg" image_open = open(path_image, 'rb') read_image = image_open.read()

Step 3 - Decode image

image_decode = tf.image.decode_jpeg(read_image) image_decode

 

Step 4 - Adjust brightness

adjust_brightness = tf.image.adjust_brightness(image_decode, delta=0.2) adjust_brightness
