Face recognition in unconstrained videos requires specialized tools beyond those developed for still images: the fact that the confounding factors change state during the video sequence presents a unique challenge, but also an opportunity to eliminate spurious similarities.
Leveraging Billions of Faces to Overcome Performance Barriers in Unconstrained Face Recognition
We employ the face recognition technology developed in house at face. com to a well accepted benchmark and show that without any tuning we are able to considerably surpass state of the art results.
