Prof Still said: “We used seven live video feeds during the inauguration and a geometric analysis. We have developed a technique which can provide scientific estimates of crowd dynamics, which has important real-world applications in the preparation of large events for crowd safety.
“On the basis that the crowd for President Obama’s inauguration was over one million people (physical counts vary for this), Trump’s was a third of the crowd size from the available, verified images. From a non-expert’s point of view, if you stand in front of a crowd it would change your perception and you would see a sea of people and possibly think the numbers are far greater. But the evidence is undeniable.”
Prof Still and Marcel, an enterprise delivery fellow, worked around the clock from 11am on the 20th - to 7am on the 22nd analysing crowds, not only for the inauguration, but also for the anti-Trump protest marches.
“The crowds for the women’s march was three times the size of those for the inauguration,” said Prof Still.
