Bayesian sparse hierarchical model for image denoising

作者：

Highlights：

• We adopt a hierarchical sparse model for image denoising.

• Our proposed method leads to the unbiased estimator for the sparse code estimation.

• Our proposed method achieves better performance on several benchmark datasets.
