Exact Decomposition of Joint Low Rankness and Local Smoothness Plus Sparse Matrices

Jiangjun Peng, Yao Wang, Hongying Zhang +2

It is known that the decomposition in low-rank and sparse matrices (\textbf{L+S} for short) can be achieved by several Robust PCA techniques. Besides the low rankness, the local sm…

Pan-denoising: Guided Hyperspectral Image Denoising via Weighted Represent Coefficient Total Variation

Shuang Xu, Qiao Ke, Jiangjun Peng +2

This paper introduces a novel paradigm for hyperspectral image (HSI) denoising, which is termed \textit{pan-denoising}. In a given scene, panchromatic (PAN) images capture similar…
