Forget Detecting Gunshots, This Camera Detects If You Just Act Violently
from the you-have-no-privacy-anywhere dept
Following the story from yesterday about sensors that can spot gunfire (which was actually old news), Search Engines WEB writes in to let us know about a new camera system being developed by researchers to automatically spot violent behavior. They claim this is different than cameras being developed and tested to simply spot suspicious behavior by looking for basic patterns. They note that such a system can often have trouble separating out certain situations. For example, they suggest that their system can tell the difference between someone offering another person a stick of gum vs. someone threatening a person with a knife -- which they claim a traditional system would view as looking pretty much the same. Currently, the system is only 80% accurate and the researchers admit it has certain limitations -- but they expect it to improve pretty rapidly over the next few years, especially as the technology gets commercialized. Of course, it will be interesting to see how people respond to such things. While you pretty much can't go anywhere these days without having surveillance cameras watching you, an awful lot of what those cameras catch is never watched or used. However, systems that can capture and analyze specific activities begin to raise many more questions. Instead of just mining consumer databases, will we be hearing stories about politicians targeting pitches to voters based on what a collection of surveillance cameras says about them?
