We've already completely conquered text searches and gained a handle on image recognition software too, but video remains to be a tricky bit. DARPA might have the breakthrough to finding untagged video with no searchable text.
DARPA's Video and Image Retrieval and Analysis Tool (VIRAT) program can supposedly perform the video-searching wonders of highlighting "specific events or activities at specific locations or over a range of locations." Lockheed Martin--whose most visible creation is the US Military's current generation warfighter, the F-35 Lighting II--was contracted by DARPA to develop a tool it could use to search through all its drone, satellites, and other surveillance archives.
There's no word on just how effective VIRAT is, but Lockheed Martin was given an undisclosed sum to ingrate the software into "various operational military-intelligence video archives and systems." So Big Brother gets an upgrade to search through its masses of surveillance video, and maybe one day it'll be easier to pick out the original Keyboard Cat from its 10,500 related videos.
