Seems like you made a point. Could you provide more details? What are the other options and who is using them?

- fxtentacle 7y agoSure, I'm happy to discuss AI in more detail. The problem is that pretty much all AIs are built upon the PWC-Net architecture from Nvidia. The solution would be to use a different architecture, but that doesn't fit into GPU. Here's the Sintel ranking: http://sintel.is.tue.mpg.de/results http://sintel.is.tue.mpg.de/results And if you look at the AIs, they all repurpose this paper: https://arxiv.org/abs/1709.0237 https://arxiv.org/abs/1709.0237 However, you cannot store one optical flow per pixel, because the solution is not unique. For example, that's why Tesla and Skydio have problems with reflective surfaces. You see both the surface and its reflection move, but the AI can only store 1 result out of those 2 movements. In my opinion, the solution is to use Fourier methods, which were shown to work well in a 2000 dagm paper called minimum values of the structure tensor. But nobody has even attempted to port that to GPU yet or use it as part of AI.
- bdamm 7y agoWell Musk did recently state that Tesla is soon to release time-based object "3d labeling", where indeed the movement of objects through space is part of their labeling.
