Super Resolution: The scaler of tomorrow, here today!

Description

Scaling. Long considered a solved problem, in this talk I’ll go over current state-of-the art results in video upscaling; how it works, what it does, and how you can start trying it out today. This talk will: – Cover the basics of video scaling, and algorithms like nearest neighbour, bilinear, bicubic and lanczos scalers – Review scaling’s impact on quality, specifically VMAF, and talk through how maximizing quality using the convex hull requires scaling – Discuss state-of-the art Super-Resolution based upscaling, and give a broad overview of how it works and where it can fit. – Highlight the downsides of super resolution, and discuss why we haven’t seen broader adoption of related techniques (hint: its performance!) – Finish with a demo of super resolution running in browser using WebGL, and discuss the open-source project that people can use to try out super resolution today. What’s special about this talk is that I’ll be evaluating super-resolution not just from the perspective of “it works!”, but with a critical eye for how these kind of techniques can fit in our current scaling stacks, and exactly how they impact quality through VMAF analysis. Presented at Demuxed 2019 in San Francisco.
