Robust Face Recognition Via Dual Nuclear Norm Low-Rank Representation And Self-Representation Induced Classifier
PROCEEDINGS OF 2018 5TH IEEE INTERNATIONAL CONFERENCE ON CLOUD COMPUTING AND INTELLIGENCE SYSTEMS (CCIS)(2018)
摘要
For robust face recognition, we particularly focus on the ubiquitous scenarios where both training and testing images are corrupted due to occlusions. In the previous low-rank based methods, each error image is stacked into a vector and formed an error matrix together, and then L1-norm or L2-norm is utilized to characterize the matrix. However, the structure information of error images will lose in the step of stacking. In this paper, we propose a novel method by utilizing a low rank hypothesis on the representation term and the error term simultaneously. For classification, we also adopt the discriminative self-representation induced classifier with more effectiveness and efficiency. Experimental results on different face recognition tasks show that our proposed method achieves comparable or superior performance to sonic state-of-the-art methods.
