The PG-URE estimator is a statistical tool that can be used to assess the performance of image denoising algorithms in presence of mixed Poisson-Gaussian noise. It was introduced in the following publication:

Yoann Le Montagner, Elsa Angelini, and Jean-Christophe Olivo-Marin, An unbiased risk estimator for image denoising in the presence of mixed Poisson-Gaussian noise, IEEE Transactions on Image Processing 23(3), pp. 1255–1268, 2014.
