Hyperspectral Image Denoising Based on Spectral Dictionary Learning and Sparse Coding

Hyperspectral Image Denoising Based on Spectral Dictionary Learning and Sparse Coding

Processing and applications of hyperspectral images (HSI) are limited by the noise component. This paper establishes an HSI denoising algorithm by applying dictionary learning and sparse coding theory, which is extended into the spectral domain. First, the HSI noise model under additive noise assump...
