We have written about computer vision and face recognition many times before, and recently one of the issues that has come has been that all the cameras in the world is to produce data that are more visual than anyone could watch. I wrote about Kitware the intention to create "behavior recognition" in the camera system, and this "Questionable Observer Detector" seems like it would be a nice complement to it.
You've heard, no doubt, a security camera that takes pictures of your face when you graduate and compare them to a central database smugglers, terrorists and other criminals. The problem is that unless these people are already known, the system can not really detect them. So the team of computer scientists at Notre Dame decided to put together a way for the database to be constructed on the fly.
The camera will analyze the recording, the recording time and place of every face in it. Then, while recording a different view, it will compare the new tracking data to the old, and see if anyone has come up twice. Someone pass the same point five times a week will be normal, but someone came and wandered in the area of the airport ticket twice a week for a month might be something to look into, regardless of whether the person's face in any database or connected with the crime.
It's a bit scary, but so is the problem it was meant to combat: the type of criminal who only need one chance to do a horrible crime - such as a suicide bomber. They will never be in the database for obvious reasons, but has a habit of checking the target several times before they attack.
Sure, it's also kind of thing that a police state would love to have in their arsenal. But one must discover sooner or later.TechCrunch latest info
