Analysis and Extension of the Percentile Method, Estimating a Noise Curve from a Single Image

Given a white Gaussian noise signal on a sampling grid, its variance can be estimated from a small block sample. However, in natural images we observe the combination of the geometry of the scene being photographed and the added noise. In this case, estimating directly the standard deviation of t...
