TL;DR

A new paper showcases a technique that allows for the generation of realistic videos from a small collection of photos, with improvements in scene rotation and anti-aliasing.

Transcript

Dear Fellow Scholars, this is Two Minute Papers with Dr. Károly Zsolnai-Fehér. Today we are going take a collection of photos like these, and magically, create a video where we can fly through these photos. So, how is this even possible? Especially that the input is only a handful of photos. Well, typically, we give it to a learning algorithm and a... Read More
