Noise parameter estimation for poisson corrupted images using variance stabilization transforms

IEEE Trans Image Process. 2014 Mar;23(3):1329-39. doi: 10.1109/TIP.2014.2300813.

Abstract

Noise is present in all images captured by real-world image sensors. Poisson distribution is said to model the stochastic nature of the photon arrival process and agrees with the distribution of measured pixel values. We propose a method for estimating unknown noise parameters from Poisson corrupted images using properties of variance stabilization. With a significantly lower computational complexity and improved stability, the proposed estimation technique yields noise parameters that are comparable in accuracy to the state-of-art methods.
