Optical networks achieve superior image denoising via pre-training

Researchers have developed a novel pre-training method for all-optical image denoising using diffractive networks. This approach involves an initial training phase with a large dataset of 3.45 million images, followed by task-specific fine-tuning. The method significantly improves denoising quality for images with severe noise, boosting PSNR from below 8 dB to over 18 dB while preserving fine details. The pre-trained network demonstrated versatility by being fine-tuned for various image types, including digits, X-rays, and faces, and proved effective in real-world vision applications like face detection and UAV localization under noisy conditions.
