Analyzing Video Analytics

A recent grant report, titled "Studying the Impact of Video Analytics for Pre, Live and Post Event Analysis of Outcomes of Criminal Justice," looks at how the growing ubiquity of surveillance cameras—and the resulting glut of video evidence—might be addressed using computer vision analytics.

The report, written by Dr. Mubarak Shah, director of the Center for Research in Computer Vision in Orlando, Florida, outlines the group's efforts to develop computer vision analytics for large surveillance camera networks, and their subsequent installation in a Public Safety Visual Analytics Workstation operating at the Orland (Florida) Police Department.

"This project aimed to develop and study the effect of computer analytics for public space surveillance camera systems. Videos from surveillance cameras have the ability to not only aid in post-event investigations but also to improve intervention in live criminal incidents by flagging them as they occur," wrote Shah. "However, when left unmonitored or poorly integrated into police departments, surveillance cameras often become useless. Currently, the number of surveillance cameras in the U.S. is increasing rapidly, with human monitoring capability unable to keep pace."
