Hyperspectral Image Classification via Kernel Sparse Representation
TLDR
In this paper, a novel nonlinear technique for hyperspectral image (HSI) classification relies on sparsely representing a test sample in terms of all of the training samples in a feature space induced by a kernel function. Expand

Joint Sparse Representation for Robust Multimodal Biometrics Recognition
TLDR
We propose a multimodal sparse representation method, which represents the test data by a sparse linear combination of training data, while constraining the observations from different modalities of the test subject to share their sparse representations. Expand

Design of Non-Linear Kernel Dictionaries for Object Recognition
TLDR
In this paper, we present dictionary learning methods for sparse signal representations in a high dimensional feature space that exploit sparsity of data in a non-linear feature space. Expand

Multi-View Automatic Target Recognition using Joint Sparse Representation
TLDR
We introduce a novel joint sparse representation based multiview automatic target recognition (ATR) method, which can not only handle multi-view ATR without knowing the pose but also has the advantage of exploiting the correlations among the multiple views of the same physical target. Expand
