How to perform tf.image.per_image_standardization on a batch of images in tensorflow : <p>I would like to know how to perform image whitening on a batch of images. </p>

<p>According to the documentation in <a href="https://www.tensorflow.org/api_docs/python/tf/image/per_image_standardization" rel="noreferrer">https://www.tensorflow.org/api_docs/python/tf/image/per_image_standardization</a>, it is said that <code>tf.image.per_image_standardization</code> takes as input a 3D tensor, that is an image, of shape: <code>[height, width, channels]</code>. </p>

<p>Is it a missing feature or there is a different method?</p>

<p>Any help is much appreciated. </p>
