It was only recently that computer systems became smart enough to identify unknown objects in photographs. Even then, it has generally been limited to individual objects. Now, two separate teams of researchers at Google and Stanford University have created software able to describe entire scenes. This could lead to much better and more intelligent algorithms in the future.

In the near term, computer vision systems that can discern the story in a picture will enable people to search photo or video archives and find highly specific images. Eventually, these advances will lead to robotic systems able to navigate unknown situations. Driverless cars would also be made safer. However, it also raises the prospect of even greater levels of government surveillance.
nice concept... as with anything new it will take some time for it to be effective and doable with a reasonable amount of resources (processing power, time, money, etc.)... many benefits (and possible setbacks) once it is ever available to video surveillance especially when monitoring large crowds...
