Face Verification Using Boosted Cross-Image Features

no code implementations28 Sep 2013 Dong Zhang, Omar Oreifej, Mubarak Shah

In contrast, we propose to extract cross-image features, i. e. features across the pair of images, which, as we demonstrate, is more discriminative to the similarity and the dissimilarity of faces.
