Hierarchical residual learning for image denoising

作者：

Highlights：

• We present a hierarchical residual learning method, which gradually increase the residual and remove these error components.

• We design a hierarchical residual learning based image noise estimation network.

• The proposed hierarchical residual learning based image noise estimation network can handle multiple image denoising tasks.
