Description

🚀 The feature

In tensorflow tf.image has a method, tf.image.resize_with_pad, that pads and resizes if the aspect ratio of input and output images are different to avoid distortion. I couldn't find an equivalent in torch transformations and had to write it myself. I think it would be a useful feature to have.

Motivation, pitch

When moving to pytoch from Tensorflow, one does not want to lose handy features!

Research direction

Start by comparing TensorFlow's tf.image.resize_with_pad behavior with the existing torch transformations. Define the expected resize and padding behavior for differing aspect ratios, then add the transform and tests that verify the output dimensions and preserved proportions.
