ANN ARBOR – Housed in Kerrytown Market & Shops, Voxel51 recently launched the Voxel51 Physical Distancing Index (PDI) to measure how the coronavirus pandemic is changing human activity in cities around the world -- in real time.

Founded by a University of Michigan professor in computer vision and his Ph.D. student who specializes in machine learning, Voxel51 uses a technique called “urban sensing” to help cities understand people, infrastructure and vehicles using expansive video camera systems like CCTV.
