With its significant performance improvements, the deep learning paradigm has
become a standard tool for modern image denoisers. While promising performance
has been shown on seen noise distributions, existing approaches often suffer
from generalisation to unseen noise types or general and real noise. It is
understandable as the model is designed to learn paired mapping (e.g. from a
noisy image to its clean version). In this paper, we instead propose to learn
to disentangle the noisy image, under the intuitive assumption that different
corrupted versions of the same clean image share a common latent space. A
self-supervised learning framework is proposed to achieve the goal, without
looking at the latent clean image. By taking two different corrupted versions
of the same image as input, the proposed Multi-view Self-supervised
Disentanglement (MeD) approach learns to disentangle the latent clean features
from the corruptions and recover the clean image consequently. Extensive
experimental analysis on both synthetic and real noise shows the superiority of
the proposed method over prior self-supervised approaches, especially on unseen
novel noise types. On real noise, the proposed method even outperforms its
supervised counterparts by over 3 dB.

通过多角度自监督解缠方法 (MeD)，本文在合成噪声和真实噪声的实验分析中展现了该方法在未见过的新噪声类型上相对于之前的自监督方法的卓越性能。在真实噪声上，该方法的性能甚至超过了其监督对照组超过 3 dB。
