Computer Count of Huge Crowds Now Possible

Getting a headcount of crowds numbering in the hundreds of thousands need not strain human eyes any longer. New software has carried out the first automated crowd count on that scale ever by analyzing aerial photographs of a huge demonstration— a time-saving innovation that could eventually help save lives and prevent disasters. The software, developed by University of Central Florida researchers, can drastically cut the time needed for crowd counts from a week to just half an hour. That represents the difference between the old method of humans painstakingly counting the number of heads per inch of aerial photograph and the new automated method. Such a speed-up in counting time could help event organizers and law enforcement decide how to safely handle huge crowds or act early to reduce the risk of stampedes and other dangers. “Automated computer analysis of such large-sc...
