Bayesian dictionary learning for hyperspectral image super resolution in mixed Poisson–Gaussian noise

作者:

Highlights:

• We propose a beta process analysis-based sparse representation regularization term.

• We learn the dictionary based on the reduced low dimension subspace.

• The dictionary learning and image estimating are unified into an formulation.

• We update the dictionary self-adaptively by variational Bayesian method.
