Deep learning technology dominates current research in image denoising. However, denoising performance is limited by target noise feature loss from information propagation association with the depth of network. This paper proposes a Dense Residual Feature Extraction Network (DRFENet) combined Enhancement Block (DEB), Dilated (RDB), (FEB), and Simultaneous Iterative Reconstruction (SIRB). The DE...
