Nuclear norm joint sparse representation for hyperspectral image classification
2017
Joint sparse representation (JSR) models have been widely applied into the field of hyperspectral image (HSI) classification. However, most of JSR-based models adopt the Frobenius norm to measure the reconstruction error, which ignores the structural information of the small patch. In this paper, we propose a nuclear-norm joint sparse representation (NuJSR) model for hyperspectral image classification. The main motivation of NuJSR is to utilize the nuclear-norm to measure the reconstruction error, so as to reflect the low-rank structural information of the small patch. To optimize our proposed NuJSR, an efficient algorithm is proposed. Experiments results confirm the effectiveness of NuJSR.
