Not exactly this type of cools stuff, but I found interesting article:
Despite their great upscaling performance, deep learning backed Super-Resolution methods cannot be easily applied to real-world applications due to their heavy computational requirements. At Collabora we have addressed this issue by introducing an accurate and light-weight deep network for video super-resolution.
To achieve a good tradeoff between computational complexity and reproduction quality, we implemented a cascading mechanism on top of a standard network architecture, producing a light-weight solution. We also used a multi-tile approach in which we divide a large input into smaller tiles to better utilize memory bandwidth and overcome size constraints posed by certain frameworks and devices. Multi-tile significantly improves inference speed. This approach can be extended from single image SR to video SR where video frames are treated as a group of multiple tiles.
We designed our solution on top of the open-source Panfrost video driver, allowing us to offload compute to the GPU.
Coming up in Part 2 of this series, we'll take a deep dive into how our model works, and how you can use free, open source software to achieve a higher level of compression than existing video compression methods. Stay tuned!
Might be interesting read, waiting for second part!
PS: as far as I understand this "AI" thing actually just 'invent' a lot of specialized algorithms on the fly (while training) and then apply them if similar situation in image occurs ?
