Enhancement of a CNN-Based Denoiser Based on Spatial and Spectral Analysis

28 Jun 2020Rui ZhaoKin-Man LamDaniel P. K. Lun

Convolutional neural network (CNN)-based image denoising methods have been widely studied recently, because of their high-speed processing capability and good visual quality. However, most of the existing CNN-based denoisers learn the image prior from the spatial domain, and suffer from the problem of spatially variant noise, which limits their performance in real-world image denoising tasks...
