Query: Collaborative representation-based robust face recognition by
  discriminative low-rank representation   We consider the problem of robust face recognition in which both the training
and test samples might be corrupted because of disguise and occlusion.
Performance of conventional subspace learning methods and recently proposed
sparse representation based classification (SRC) might be degraded when
corrupted training samples are provided. In addition, sparsity based approaches
are time-consuming due to the sparsity constraint. To alleviate the
aforementioned problems to some extent, in this paper, we propose a
discriminative low-rank representation method for collaborative
representation-based (DLRR-CR) robust face recognition. DLRR-CR not only
obtains a clean dictionary, it further forces the sub-dictionaries for distinct
classes to be as independent as possible by introducing a structural
incoherence regularization term. Simultaneously, a low-rank projection matrix
can be learned to remove the possible corruptions in the testing samples.
Collaborative representation based classification (CRC) method is exploited in
our proposed method which has closed-form solution. Experimental results
obtained on public face databases verify the effectiveness and robustness of
our method.
