Resize image for nd

[ruanxt]

Is there a functionality of resize image for n-d where n > 2? It seems currently tensorflow only support resize images for 2d images (4D tensor). Could you add the functionality?

This is a fine feature request. Since it's a somewhat niche feature, we will not be able to work on this soon, but if someone else wants to take this on, I'd support it.

Though adding dimensions is outside the scope of tf.image in TensorFlow Core, it might be a welcome addition to the image operations in TensorFlow Addons. If you haven't already seen it, I'd also strongly recommend taking a look at TensorFlow Graphics! 😄

Transferring this issue to tensorflow/addons; @seanpmorgan for visibility.

Hmmm this one I'm less confident in adding to addons as opposed to modifying tf.image.resize. There would be no functionality difference only that it would support larger rank tensors. I don't believe this would be adding dimensions, just resizing higher dimensional tensors so I would be interested in hearing why tf.image.resize can't be modified before adding a tfa.image.resize_nd which esentially does the same thing.

Closing this issue as I do not see it as a separate addition, but rather an extension to tf.image.resize. Happy to have someone re-open this and discuss why it should be an addon instead.
