自监督真实世界图像去噪仍是一项基本挑战,源于对空间结构噪声去相关与保留高频细节之间的对抗性权衡。现有的盲点网络(BSN)方法依赖像素洗牌下采样(PD)来对噪声去相关,但激进的下采样会碎片化精细结构,而较温和的下采样则无法去除相关噪声。为解决这一问题,我们引入下一尺度预测(NSP),一种新颖的自监督范式,将噪声去相关与细节保留解耦。NSP构建跨尺度训练对,其中BSN以低分辨率、完全去相关的子图像作为输入,预测保留精细细节的高分辨率目标。作为副产品,NSP无需重新训练或修改即可自然支持噪声图像的超分辨率。大量实验表明,NSP在真实世界基准上达到了最优的自监督去噪性能,显著缓解了噪声去相关与细节保留之间长期存在的冲突。代码可在 https://github.com/XLearning-SCU/2026-CVPR-NSP 获取。

Self-supervised real-world image denoising remains a fundamental challenge, arising from the antagonistic trade-off between decorrelating spatially structured noise and preserving high-frequency details. Existing blind-spot network (BSN) methods rely on pixel-shuffle downsampling (PD) to decorrelate noise, but aggressive downsampling fragments fine structures, while milder downsampling fails to remove correlated noise. To address this, we introduce Next-Scale Prediction (NSP), a novel self-supervised paradigm that decouples noise decorrelation from detail preservation. NSP constructs cross-scale training pairs, where BSN takes low-resolution, fully decorrelated sub-images as input to predict high-resolution targets that retain fine details. As a by-product, NSP naturally supports super-resolution of noisy images without retraining or modification. Extensive experiments demonstrate that NSP achieves state-of-the-art self-supervised denoising performance on real-world benchmarks, significantly alleviating the long-standing conflict between noise decorrelation and detail preservation.
