From density.io:

I wonder how true this statement is, given how accurately we can now identify people based on just their walking gait – see "Human Gait Recognition Based on Gait Energy" paper[1].

The 'sensor' view on density.io that attempts to illustrate this point appears to convey just as much as the sample images in the paper.

We get this question from time to time. It may be possible with some systems but it's not feasible at our resolution. You can see more of our depth data here -- https://medium.com/density-inc/ai-is-not-magic-its-manual-la...

I'll have to take your word for it – I'm curious if you have tried it though. I can certainly imagine that it might be feasible (even at lower resolutions) with enough stirring of the 'linear algebra pile'.

Not meaning to rain on your parade though – congratulations on a great idea!

No rain! It's a great callout. We'll see what we can do if for no other reason than to understand risk.
