Recipe Objective

How to crop a image using tf?

This is achieved by using "tf.image.crop_and_resize" function available in tensorflow. This function extracts the crop from the input image tensor and resizes them. By using nearest neighbor sampling or bilinear sampling the extraction is done to a common output size specified by the crop_size.

Step 1 - Import library

import tensorflow as tf

Step 2 - Take Sample image

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

Step 3 - Decode image

decode = tf.image.decode_jpeg(read_image) decode

 

Step 4 - Expand decoded image

expand = tf.expand_dims(decode, 0) expand

 

Step 5 - Crop the image crop = tf.image.crop_and_resize(expand, boxes=[[0.0, 0.0, 0.5, 0.5]], crop_size=[256, 256], box_indices=[0]) crop
