YeTI framework generates realistic image noise from two noisy images

By PulseAugur Editorial · [2 sources] · 2026-07-10 08:33

Researchers have developed YeTI, a novel framework for generating realistic sRGB noise for image denoising tasks. This method learns to synthesize signal-dependent noise using only two noisy images of the same scene, eliminating the need for clean ground truth data or camera metadata. YeTI employs a Reconstruction Autoencoder and a Conditional Diffusion Transformer to disentangle scene structure from noise characteristics, enabling the generation of realistic noise that preserves underlying image content. Experiments show that denoisers trained with YeTI-synthesized images achieve strong real-world performance on various benchmarks, including SIDD and DND. AI

IMPACT Enables more robust image denoising models by providing a scalable method for generating realistic training data without requiring clean images.
