SPAD-Net: Structure-Preserving Photoelectron- Adaptive Denoising Network for Low-Exposure ARPES Image
Low-exposure angle-resolved photoemission spectroscopy (ARPES) images are strongly affected by Poisson-Gaussian noise, which degrades band boundaries and peak shapes and reduces the reliability of physical interpretation. However, most existing methods primarily perform denoising by minimizing pixel-wise errors. As a r...
