Zero-Shot Noise2Mean: Gap Minimization for Efficient Denoising from a Single Noisy Image

AAAI 2025technical

Acquiring pairwise noisy-clean training data is challenging. Consequently, some self-supervised denoising methods utilize noisy image pairs as both input and target for network training. However, a major issue with these methods is the gap between the clean images of the input and target. In this pa…
