Query: Occlusion Robust Face Recognition Based on Mask Learning with
  PairwiseDifferential Siamese Network   Deep Convolutional Neural Networks (CNNs) have been pushing the frontier of
the face recognition research in the past years. However, existing general CNN
face models generalize poorly to the scenario of occlusions on variable facial
areas. Inspired by the fact that a human visual system explicitly ignores
occlusions and only focuses on non-occluded facial areas, we propose a mask
learning strategy to find and discard the corrupted feature elements for face
recognition. A mask dictionary is firstly established by exploiting the
differences between the top convoluted features of occluded and occlusion-free
face pairs using an innovatively designed Pairwise Differential Siamese Network
(PDSN). Each item of this dictionary captures the correspondence between
occluded facial areas and corrupted feature elements, which is named Feature
Discarding Mask (FDM). When dealing with a face image with random partial
occlusions, we generate its FDM by combining relevant dictionary items and then
multiply it with the original features to eliminate those corrupted feature
elements. Comprehensive experiments on both synthesized and realistic occluded
face datasets show that the proposed approach significantly outperforms the
state-of-the-arts.
