论文摘要

基于深度学习的图像DeNoisising方法由于其性能的提高而最近很受欢迎。传统上,这些方法是以监督的方式进行训练的,需要一组嘈杂的输入和清洁目标图像对。最近,已经提出了一种自我监督的方法来学习仅从嘈杂的图像中学习deno。这些方法假定跨像素的噪声在统计上是独立的,并且基础图像像素在社区之间显示空间相关性。这些方法依赖于将图像像素分为两个不相交集的掩蔽方法,其中一种方法被用作网络的输入,而另一种则用于定义损失。但是,这些先前的自我监督方法依赖于纯粹的数据驱动的正则化神经网络,而无需明确考虑掩盖模型。在这项工作中,以这些自我监督的方法为基础,我们介绍了Noise2Inpaint(N2I),这是一种训练方法,将denoising问题重新提到了正规图像涂层框架。这使我们可以使用目标函数,该功能可以根据需要结合噪声的不同统计属性。我们使用算法展开来展开迭代优化,以求解此目标功能并训练展开的网络端到端。训练范式遵循以前作品的掩盖方法,将像素分为两个不相交组。重要的是,其中一个现在用于在展开的网络中施加数据保真度,而另一个仍定义了损失。我们证明,N2i在现实世界数据集上成功进行了成功,同时与纯粹由数据驱动的对应物噪声2自己相比,更好地保留了细节。

Deep learning based image denoising methods have been recently popular due to their improved performance. Traditionally, these methods are trained in a supervised manner, requiring a set of noisy input and clean target image pairs. More recently, self-supervised approaches have been proposed to learn denoising from only noisy images. These methods assume that noise across pixels is statistically independent, and the underlying image pixels show spatial correlations across neighborhoods. These methods rely on a masking approach that divides the image pixels into two disjoint sets, where one is used as input to the network while the other is used to define the loss. However, these previous self-supervised approaches rely on a purely data-driven regularization neural network without explicitly taking the masking model into account. In this work, building on these self-supervised approaches, we introduce Noise2Inpaint (N2I), a training approach that recasts the denoising problem into a regularized image inpainting framework. This allows us to use an objective function, which can incorporate different statistical properties of the noise as needed. We use algorithm unrolling to unroll an iterative optimization for solving this objective function and train the unrolled network end-to-end. The training paradigm follows the masking approach from previous works, splitting the pixels into two disjoint sets. Importantly, one of these is now used to impose data fidelity in the unrolled network, while the other still defines the loss. We demonstrate that N2I performs successful denoising on real-world datasets, while better preserving details compared to its purely data-driven counterpart Noise2Self.
