Abstract Nonlocal property is an important feature of natural images, which
means that the patch matrix formed by similar image patches is low-rank.
Meanwhile, learning good image priors is of great importance for image
denoising. In this paper, we combine the image self-similarity with EPLL
(Expected patch log likelihood) method, and propose an EPLL denoising model
based on internal and external image similarity to improve the preservation of
image details. The experiment results show that the validity of our method is
proved from two aspects of visual and numerical results. More >
