Researchers have developed a new approach for Gaussian color image denoising, focusing on data-centric training and self-ensemble techniques rather than novel model architectures. By expanding the training dataset with larger and more diverse public image corpora and implementing a two-stage optimization process, they significantly improved performance. The method achieved a PSNR of 30.762 dB and SSIM of 0.861 on the NTIRE 2026 challenge validation set, outperforming the baseline Restormer model by over 3 dB. AI
