Motivation

With the increasing pervasiveness of digital cameras, the Internet, and social networking, there is a growing need to catalog and analyze large collections of photos. Because photo interest is largely determined by who appears in the picture, labeling photos with identities is particularly important. In fact, popular social networks such as Facebook allow users to place tags on photos to label people, encouraging collaboratively organized photo albums amongst friends. Imagine millions of social network users needing to tag their photos: such web-scale labeling problems present a real challenge and fascinating opportunity for automation by face recognition.

Results

Precision-recall curves for thirteen methods on PubFig+LFW and on Facebook; the SRC-based curves sit highest in both panels, and LASRC tracks standard SRC closely

SRC based methods outperform all other methods in terms of precision and recall. It is important to notice that our method performs comparably to standard SRC, but with a 100x speedup as seen in the timing diagram below.

A time budget from 0 to 125 milliseconds: SHORE detection takes the first 30 ms, eye alignment and Gabor, LBP and HOG features run to 60 ms, and the recognition step varies by method, with LASRC finishing near 90 ms and KNN-SRC slowest past 120 ms

Timeline of all steps in the entire face recognition system. All times reported with a single core of a 2.27 GHz machine.
