The Tech Behind the Capture of the Boston Bombing Suspects

Posted: Updated:

Only on FOX 11, an explanation of how the FBI was able to rapidly process some four thousand hours of security, news and personal videos of the Boston bombings.  Walter O'Brien of Scorpion Computer Services in Burbank explains video forensics. The first task is to separate the meaningful video from footage that isn't useful.

That winnowed down the four thousand hours down to a more manageable 20 hours. O'Brien explains the programs then use edge detection to separate static video from people, then flow analysis is done to show the motion of those people.

When the FBI first released the video of their suspects, agents explained that the focused on a man now known as Dzhokhar because he didn't react to the explosion, while everyone else, did and that made him stick out.
