Researchers have developed a real world counterpart to Harry Potter's magical marauder's map.
The map system was devised at Carnegie Mellon and replaces magic with a bit of computer wizardry. The data from a number of security cameras around a building is analyzed by a set of special algorithms which use facial recognition, color matching and location tracking to determine where each individual is located. The resulting co-ordinates are then displayed on a map in real-time.
The system is unique because it uses several sources of information to plot a person's whereabouts and does not require that person to be carrying a tracking device. "An ideal Marauder's Map algorithm should integrate different sources of information," the research team wrote in a paper covering their findings. "Our algorithm is effective because of reliable face recognition and the combination of manifold learning with nonnegative discretization."
"With homage to the fictional map used by Harry Potter, they came up with a solution that can effectively track people in the real world just like The Marauder's Map locates and tracks people in Harry Potter's magical world."
