I wonder what it might detect if we feed it video of prominent people at various engagements over the past year. Especially if these same prominent people were noted over the last two years at some period of time to be strangely absent from public events.
It honestly sounds like bullshit to me. Tracking blood flow from a shitty internet video? Come on. This will probably become their way to "fact check" videos they want to discredit.
The human heart generates a blood volume pulse (BVP) with each beat and is the source of the blood circulation. The resulting blood flow through the circulatory system leads to a continuous change in skin color. This effect can be observed more strongly when a person is physically active, e.g., after climbing stairs. The heart rate rises and the face color is getting redder. However, this constant color change is mostly imperceptible for the human eye. With rPPG techniques, this color variation is detected from a video, and the pulse rate can be determined.

Then again actors don't need to be cgi.
That's an interesting thought. Latex masks don't have blood flow either, so it would detect them as deep fakes...
But holograms do... I remember disappearing pope on the balcony
Hmm, getting ahead of something?
Probably, but needs to be open source. If the public can't run it, we can't verify it.

This isn't some Intel-exclusive wizardry. It's just analyzing changes in the red color channel over time:

How do we get Biden videos reviewed?
We'll just have to trust the authority on what is real and what is not.
