Hitachi's next-generation facial-recogition technology involves the searching and matching of 36 million faces in a second. The software can instantly match live, still or video images with other images stored in a database. The database can consist of archived surveillance video from a retail store, a bank or a large police database. Each match result will be displayed in its native format, which allows the playback of the video prior to and after the person was captured by the surveillance camera. For example, if a person robs a convenience store, and he has visited the store on prior occasions, the software can match his face to his other visits. Investigators can watch the archived video to deduce clues to his identity, such as if he used a credit card. In addition, his face can also be scanned for in a large crowd, such as in a transit security system's database.
Also, according to Wired.com, the Navy, in a partnership with StereoVision Imaging, is developing 3-D binoculars that can recognize faces up to 650 feet away. Using a wireless network, the binoculars transmit images to a database for real-time identification. StereoVision already has binoculars, called 3DMobileID, that can do this, but up to 328 feet.
