Automatic Parameter Prediction For Image Denoising Algorithms Using Perceptual Quality Features
HUMAN VISION AND ELECTRONIC IMAGING XVII(2012)
摘要
A natural scene statistics (NSS) based blind image denoising approach is proposed, where denoising is performed without knowledge of the noise variance present in the image. We show how such a parameter estimation can be used to perform blind denoising by combining blind parameter estimation with a state-of-the-art denoising algorithm. 1 Our experiments show that for all noise variances simulated on a varied image content, our approach is almost always statistically superior to the reference BM3D implementation in terms of perceived visual quality at the 95% confidence level.
