2-Shots in the Dark: Low-Light Denoising with Minimal Data Acquisition

arXiv — cs.CVThursday, December 4, 2025 at 5:00:00 AM
  • A new method for low-light image denoising has been proposed, which requires minimal data acquisition by synthesizing noise from a single noisy image and a dark frame per ISO setting. This approach utilizes a Poisson distribution to model signal-dependent noise and a Fourier-domain spectral sampling algorithm for signal-independent noise, aiming to improve image quality in challenging lighting conditions.
  • This development is significant as it addresses the limitations of traditional learning-based denoisers that rely on large datasets of clean and noisy images, which are often difficult to obtain. By reducing the data requirements, this method can facilitate advancements in various applications, including photography and surveillance, where low-light conditions are prevalent.
  • The introduction of this noise synthesis technique aligns with broader trends in artificial intelligence, where efficiency and data minimization are critical. Similar advancements in areas such as dataset distillation and diffusion models highlight a growing emphasis on optimizing machine learning processes, potentially leading to faster and more effective image processing technologies.
