The system will look at a person's walking style including hand movements and stride — collectively known as gait recognition — and once it has been identified, the system can see whether the footage from other CCTV cameras offers up a match.
"Necessity is the mother of invention" is a silly proverb. "Necessity
is the mother of futile dodges" is much nearer the truth.
