Convolution Transpose and Sub-pixel Convolution

I read an interesting paper called Photo-Realistic Single Image Super-Resolution Using a Generative Adversarial Network.
I am having some difficulty understanding the concept of "Pixel Shuffle", which uses sub-pixel convolution to upscale the input images in the final layer.

If anybody could explain how exactly the sub-pixel and transpose convolution operations are performed, I'll be very thankful.

P.S. I referred to this document too, but it didn't help much.

Hey there!

I am Utkarsh Verma, a senior undergrad at Delhi Technological University, Delhi, India. I just got to know about Machine Learning/AI recently and I am taking the Udacity course on deep learning using pytorch currently. I am liking it this far, and hope to collaborate with some of the members to work on some interesting projects and to get to know about the opportunities around the globe.

Cheers!
