Abstract: Sparse Representation Classifier (SRC) and Kernel Discriminant Analysis (KDA) are two successful methods for face recognition. SRC is good at dealing with occlusion while KDA does well in suppressing intra-class variations.
In this paper, we propose Kernel Extended Dictionary (KED) for face recognition, which provides an efficient way for combining KDA and SRC. We first learn several kernel principal components of occlusion variations as an occlusion model, which can represent the possible occlusion variations efficiently. Then the occlusion model is projected by KDA to get the kernel extended dictionary, which can be computed via the same ``kernel trick" as new testing samples.
Finally, we use structured SRC for classification, which is fast as only a small number of atoms are appended to the basic dictionary and the feature dimension is low. We also extend KED to multi-kernel space to fuse different types of features at kernel level. Experiments are done on several large-scale datasets, demonstrating that not only does KED get impressive results for non-occluded samples, but it also handles occlusion well without overfitting, even with a single gallery sample per subject.
