Dahua is irresponsibly marketing for safe city projects. See video below:
It starts off strangely with a woman being stabbed for no clear reason:
Then they track his car via LPR, which is possible:
Than they get a hit on the car via LPR. Notice the shot below and the absurdity it foreshadows:
The guy gets out of his car and they lost him.... but no....
That's right. They create a high quality facial model off of a video feed of a person inside a speeding car, at night, wearing a ballcap.
This is some serious science fiction. This is not a criticism of face recognition as much as basic image capture impossibility. You are not getting such a high quality facial shot from such a scenario.
To top it off, they take a 1080p camera mounted some 30+ feet in the air:
Of course, they get a facial recognition match on the suspect at night, in a shadow, with a hat on from a 1080p camera across the road.
Dahua is certainly not the first marketer to engage in such fiction (recall: Abu Dhabi Is a Very Safe City) so this is certainly not an innovation.
However, this is not the type of expectations we should be setting for technology.
