OK. So they have millions of faces in the Big Face Data Base.
If they have a single face image with which to search the facial data base to find a matching image and associated information for that face it is like doing a Google search.
What if the NSA wants to search hundreds or thousands of faces in a single extremely high resolution image such as those discussed in the prior blog entry. Faces in a crowd that has formed for some purpose. A football game, a rock concert, a mass protest.
Get the picture?
I expect that the NSA/CIA/Homeland Security has already tested out the idea.
I recall a news item from many years ago test facial recognition at large sports events. An image data base of people, maybe felons or other persons wanted by law enforcement was used to screen images of people entering/leaving a major sports event attended by thousands. Maybe there was more to the exercise.
This would be a good way to test the level of performance and ID accuracy of the types of extremely high resolution taken by cameras of the large audience event. Take pictures of the spectators. Index distinguishing image ID elements of each spectator. Have cameras at the exit screen spectators departing to match to the previously recorded indexed spectator images. Learn how well the image identification system using ultra high resolution cameras to record all spectator facial images identifies that same person when they leave.
