Spanish researchers have developed a system that can be tracked wherever a video is recorded. The program can be important in the fight against IS. In this way, the executioners of the terrorist movement can be detected.
The program built researchers at the Ramon Llull University in Barcelona, uses a localization technique that recognizes audiovisual data from a global database of image and sound.
,, Audio is just as useful as visual information, sometimes even more valuable. Next, we use mathematical methods to determine a location. This has already succeeded several times “, Xavier Sevillano tells the Daily Mail.
algorithm
Many of the videos that are on the Internet have an accompanying text on the location, time and other details. But that does not apply to any movie. When that is the case, all data will be merged, and an algorithm is released there. In this way the data can be compared with a set of global videos that are already is located.
Although the system is innovative and can be useful in the fight against IS should not be too soon there. Only three percent of the videos can be traced to a location three kilometers deviates from the actual location. One percent of the videos can be determined exactly on the kilometer.
More effective growth
To make the system more effective, the database must be greater be. Provided that succeeds, it may in the future be very useful for business loss, disappearance or other calamities. The condition is that there must be recent video on the Internet. This can also be a film that is shared on social media.
