Jan 19 at 3:46 comment added ayr I think you're right. I can start with short films. To gain basic skills. And the rest of the base will be added in the process. Thank you for your response and for your time!
Jan 18 at 8:53 comment added Neil Slater @dtn I suggest you start with a naive system based around your initial idea. Building it and experiencing the issue with temporal coherence and frame rate first hand will be valuable experience, and far more rewarding than trying to build the most sophisticated version you read about as the first attempt. Once you have a basic version, then you can refer to ideas in this answer to upgrade it
Jan 18 at 5:26 comment added ayr In general, I would like to study the issue at such a level that I could experiment with the upscale of some old films, which are now perceived completely differently than before... Well, and get some results and practical knowledge.
Jan 17 at 15:29 comment added Neil Slater @dtn: There are quite a few different approaches, and different kinds of models used to solve these problems. So there isn't a specific structure, it's more about how deep you want to look into the issue. Similar is true for image upscaling in the first place. A simple model is to linearly interpolate to get values for missing pixels. Slightly more sophisticated is to use bicubic interpolation. Wavelet decomposition. The modern AI-based upscalers don't do any of that, and even looking at the generative model upscalers, there are GAN-based, Diffusion-based etc. No single model or structure
Jan 17 at 14:58 comment added ayr Well, I think that using the keywords from your answer I will find enough information to study.
Jan 17 at 14:56 comment added ayr Thank you! The “physics of the process” and related problems are clear to me. But the block diagrams and mathematics underlying the methods for increasing temporal coherence and increasing frame rates need to be studied separately. Because, as I understand it, GAN in its pure form is not used for this. Therefore, surely those models that solve both problems have a specific structure?
