Poisson2Poisson-Sparse: Unsupervised Poisson noise image denoising based on sparse modeling

In fields such as low-light photography, astronomical imaging, and low-dose computed tomography scanning, Poisson noise severely degrades image quality due to extremely low photon counts (averaging below one) and their Poisson-distributed statistical characteristics. A recent self-supervised Poisson...
